2012-09-25Merge tag 'iio-for-v3.7e' of ↵Greg Kroah-Hartman
git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Fifth round of new drivers and device support for the IIO subsystem in the 3.7 cycle. Here we have a mixed bag of new stuff, minor fixes and more major fixes for drivers added earlier in this cycle. 1) A number of fixes for the HID sensors code added in previous pull request. Typical stuff that has become apparent as more eyes have looked at the code post merging. Similar case for the ad5755 dac. 2) Cleanups of error handing in inkern.c - again typical stuff to see as code comes into heavier use and people notice the naughty short cuts that snuck in originally and kindly fix them. 3) A series from Lars that removes some incorrect error handling from the remove functions of a number of drivers. These have been there for a very long time hence I'm not pushing these out for the 3.6 cycle. 4) Support for more parts in the ad7780 driver. 5) A driver for the adcs on the lp8788 power management unit 6) A client driver for IIO to allow it's ADCs to be used for battery status measurement. Note this driver has some dependencies on some utility functions added to IIO in this series, hence it is coming via this tree rather than Anton's. 7) A null pointer dereference bug in the 'fake' driver. I'm not doing this as a fix for the 3.6 cycle because it only effects 'fake' hardware and that code is typically only used by people investigating how IIO works as part of writing new drivers. Hence it's hardly a critical fix.

2012-09-22staging:iio:dummy: Fix potential NULL pointer dereferenceLars-Peter Clausen
If the config contains CONFIG_IIO_BUFFER=y and CONFIG_IIO_SIMPLE_DUMMY_BUFFER=n iio_simple_dummy_configure_buffer() is stubbed out and iio_buffer_register() is not. As a result we try to register a buffer which has not been configured. This will causes a NULL pointer deref in iio_buffer_register. To solve this issue move the iio_buffer_register() call to iio_simple_dummy_configure_buffer(), so it will only be called if iio_simple_dummy_configure_buffer() has been called.

2012-09-22power: battery: Generic battery driver using IIOanish kumar
Driver to allow use of the ADC drivers supported by the IIO subsystem for battery status monitoring. Connecting this driver to the relevant IIO device requires registration of the appropriate iio_map structure array by the IIO device driver (usually from platform data). If specified the driver will also make use of a gpio to provide interrupt driven notification that the battery is fully charged. In last version: Addressed concerns raised by lars: a. made the adc_bat per device. b. get the IIO channel using hardcoded channel names. c. Minor issues related to gpio_is_valid and some code refactoring. In V1: Addressed concerns raised by Anton: a. changed the struct name to gab(generic adc battery). b. Added some functions to neaten the code. c. Some minor coding guidelines changes. d. Used the latest function introduce by lars: iio_read_channel_processed to streamline the code. In V2: Addressed concerns by lars: a. No need of allocating memory for channels.Make it array. b. Code restructring, coding style and following kernel guidelines changes suggested by him. In V3: Addressed conerns by Anton: a. Added the copyright. b. Coding guidelines changes suggested by him. c.

2012-09-22iio: adc: add new lp8788 adc driverKim, Milo
TI LP8788 PMU provides regulators, battery charger, ADC, RTC, backlight driver and current sinks. This patch enables the LP8788 ADC functions. The LP8788 ADC has several ADC input selection and supports 12bit resolution. Internal operation of getting ADC is access to registers of LP8788. The LP8788 ADC uses exported functions for accessing these registers. (exported by LP8788 MFD device driver) This driver supports IIO_CHAN_INFO_RAW and SCALE. So the IIO consumer can calculate the value with raw and scale. The unit of scale is micro. (ADC Input Selection) Voltage: battery voltage (MAX 5.0, 5.5 and 6.0V) charger input voltage four general ADC inputs coin cell voltage Current: battery charging current Temperature: IC temperature (The IIO map for the IIO consumer) The ADC input is configurable in the platform side. Even though this platform data is not defined, the default IIO map is created for supporting the power supply driver. The battery voltage and temperature are used inside this driver. (History) Patch v6. (a) Fix scale value for each ADC input selection Voltage and current type are mili unit and temperature is degree. To calculate the IC temperature, temp = raw * scaleint + (raw * scalepart)/ 1000000, scaleint is always 0. = raw * 0.061050, raw: 0 ~ 4095 Then range of IC temperature(ADC result) is 0 ~ 250'C (b) Reorganization of the IIO channel Spec Remove address, scan_type and scan_index and rollback the datasheet name. The reason why 'address' field is unnecessary is no relation with each channel. Moreover, to get the raw ADC value, the address info is not only one register but also several registers. Therefore specific function(lp8788_get_adc_result) is called rather than using one 'address' field. (c) Fix coding style Remove duplicated checking routine while unregistering the IIO map. Fix code for space and parenthesis. Patch v5. Fix default consumer name as 'lp8788-charger'. Add mutex for ADC read operation. Reorganization on lp8788_adc_read_raw(). Patch v4. Fix adc_raw function: support RAW and SCALE channel info. Change LP8788 ADC platform data - iio map. Enables the default IIO map. Patch v3. Fix wrong size of allocating iio private data. Fix coding styles. Patch v2. Support RAW and SCALE interface for IIO consumer. Clean up the iio channel spec macro.

2012-09-22iio: inkern: clean up error return codeKim, Milo
When the IIO consumer tries to get specific IIO channel, few error cases can be happened. (a) Memory allocation failure (b) No matched ADC channel error (c) Invalid input arguments This patch enables cleaning up error handling in case of (a) and (b). In error handling code, (a): the reference count of the IIO device should be decreased. (b): the allocated memory should be freed with restoring the reference count. Therefore iio_deivce_put() is called in both cases. This can be handled in the last error statement. Additionally, integer variable is used for stating each error case explicitly. Then, the error returns as ERR_PTR() with this value. Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2012-09-22iio: hid-sensors: Prevent crash during hot-unplugSrinivas Pandruvada
When hid sensor hub is unplugged, there is a crash in iio_device_unregister_trigger_consumer. In a typical IIO driver when remove is called, it will unregister and free trigger and then it will call iio_device_free. The function iio_trigger_free() will free the allocated memory for trigger. If this trigger was assigned to iio_dev->trig, then it should be set to NULL. Othewise when iio_device_free() is called later, it finally calls iio_device_unregsister_trigger(), which checks for if (indio_dev->trig) iio_trigger_put(indio_dev->trig); If indio_dev->trig is not set to NULL, it calls iio_trigger_put on a bad pointer causing crash. This scenerio can happen in any driver, which is storing trigger pointer in iio_dev structure and following current procedure during remove.

2012-09-21staging: comedi: fix memory leak for saved channel listIan Abbott
When `do_cmd_ioctl()` allocates memory for the kernel copy of a channel list, it frees any previously allocated channel list in `async->cmd.chanlist` and replaces it with the new one. However, if the device is ever removed (or "detached") the cleanup code in `cleanup_device()` in "drivers.c" does not free this memory so it is lost. A sensible place to free the kernel copy of the channel list is in `do_become_nonbusy()` as at that point the comedi asynchronous command associated with the channel list is no longer valid. Free the channel list in `do_become_nonbusy()` instead of `do_cmd_ioctl()` and clear the pointer to prevent it being freed more than once. Note that `cleanup_device()` could be called at an inappropriate time while the comedi device is open, but that's a separate bug not related to this this patch.

This fixes a number of sparse warnings like: warning: incorrect type in argument 2 (different address spaces) expected void volatile [noderef] <asn:2>*addr got void * warning: incorrect type in argument 1 (different address spaces) expected void const volatile [noderef] <asn:2>*addr got void *<noident> Signed-off-by: H Hartley Sweeten <hsweeten@visionengravers.com> Cc: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-09-21staging: comedi: kcomedilib: fix a __user space access issueH Hartley Sweeten
The 'data' field in struct comedi_insn is an unsigned int __user *. The comedi core copies this data to kernel space before passing it on to a drivers insn_bits/insn_config method. kcomedilib provides an interface for external kernel modules to use the comedi drivers. This interface creates a comedi_insn that is then passed to the comedi drivers insn_bits/insn_config method. Unfortunately, kcomedilib is using the comedi_insn 'data' field directly which results in some sparse warnings: warning: incorrect type in argument 4 (different address spaces) expected unsigned int *<noident> got unsigned int [noderef] <asn:1>*data warning: incorrect type in assignment (different address spaces) expected unsigned int [noderef] <asn:1>*[addressable] [assigned] data got unsigned int *<noident> Fix this by passing the kernel data directly, as a separate parameter, instead of trying to put in into the comedi_insn 'data' field. This is how the comedi core handles the data from user space.

2012-09-21staging: comedi: me_daq: use attach_pci callbackH Hartley Sweeten
Convert this PCI driver to use the comedi PCI auto config attach mechanism by adding an 'attach_pci' callback function. Since the driver does not require any external configuration options. and the legacy 'attach' callback is now optional, remove it. Also, make the boardinfo 'name' unique for the different board types. Use this name when requesting the PCI resources. Change the printk at the end of the attach into a dev_info.

2012-09-21staging: comedi: me_daq: use request_firmware()H Hartley Sweeten
This driver requires loading a firmware file for the fpga. This is currently being done by passing the firmware data using the COMEDI_DEVCONFIG ioctl through the attach() hook in the driver. This does not work for auto-configured PCI devices due to the firmware loading options not being set in the comedi_devconfig parameter passed to the driver. Change the driver so it gets the firmware using request_firmware() and ignore any firmware options passed in the comedi_devconfig.

2012-09-21staging: comedi: usbdux: remove usbdux_attachH Hartley Sweeten
This driver originally used the 'attach' method in order to get the firmware for the device from the comedi_config utility. It now uses request_firmware_nowait() in the usb_driver probe to get this firmware. Since this driver has an 'attach_usb' method in the comedi_driver, the 'attach' method can be removed because it is now optional.
