git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First set of new drivers, cleanups and functionality for IIO in the 4.1 cycle. New drivers * CM3323 color sensor. * MS5611 pressure and temperature sensor. New functionality * mup6050 - create mux clients for devices described via ACPI. The reasoning and approach taken in this patch are complex. Basically there is no otherway of finding out what is there than by some esoteric look ups in the ACPI data. * cm3232 - PM support * itg3200 - suspend/resume support * mcp320x - add more ADCs to the kconfig to reflect what the driver supports (this patch and the bindings got left behind when the support was added a while back). Docs / utils * ti-adc128s052 - DT bindings. * mcp3422 - DT bindings. * mcp320x - DT bindings * ABI docs for event threshold scale attributes, in_magn_offset, proximity scan_element and thresh falling/rising values for accelerometers. All elements long in use that have slipped by being explicitly documented. * Tidy up the tools previously in drivers/staging/iio/Documentation and move them out to /tools/iio. Yet another move that should have happened long ago. This time Roberta Dobrescu did the leg work. Thanks! Core Cleanups * Export userspace IIO headers. We should have done the appropriate header splitting a long time ago. Thanks to Daniel for sorting this out. * Refactor the registring of attributes for buffers to move all non-custom ones to a vector allowing easier additions to the current set in the future. Driver Cleanups * gpiod related cleanups. Make use of the additional parameter to specify initial direciton to avoid extra code. * bmc150 - Various refactorings to reduce code repitition and prepare for hardware buffer support. Some of these cleanups are good even without the new functionality. * kmx61 - direct use of index to an array avoiding a structure element which was always the index to an element in an array of that structure. * vf610 - avoid incorrect type for return from wait_for_completion_timeout. * gp2ap020a00f - use put_unaligned_le32 for slight code simplification. * ade7754 - improve error handling including suppressing some build warnings. * ade7759 - improve error handling including suppressing some build warnings. * hmc5843 - Long line and indentation fixes. Also some constifying of various constant data. * ade7854 - 80+ character line splitting. * ad2s1210 - fix wrong printf format string. * mxs-lradc - fix wrong printf format string. * ade7954-i2c - code alignment fixes and other trivial but worthwhile bits. * periodic rtc trigger - make the frequency type an unsigned int as it is always treated as such. * jsa1212 - constify struct regmap_config as it is constant. * ad7793 - typo in the MODULE_DESCRIPTION * mma9551 - check gpiod_to_irq errors. Note that this doesn't actually cause any trouble but is worth tidying up as obviously incorrect. * mlx90614 - refactor the register symbols to make it clear which reads are to RAM not PROM.
2015-03-16Staging: iio: use !x instead of x == NULLSomya Anand
Functions like devm_kzalloc, kmalloc_array, devm_ioremap, usb_alloc_urb, alloc_netdev return NULL as a return value on failure. Generally, When NULL represents failure, !x is commonly used. This patch cleans up the tests on the results of these functions, thereby using !x instead of x == NULL or NULL == x. This is done via following coccinelle script: @prob_7@ identifier x; statement S; @@ ( x = devm_kzalloc(...); | x = usb_alloc_urb(...); | x = kmalloc_array(...); | x = devm_ioremap(...); | x = alloc_netdev(...); ) ... - if(NULL == x) + if(!x) S Further we have used isomorphism characteristics of coccinelle to indicate x == NULL and NULL == x are equivalent. This is done via following iso script.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging Pull staging driver updates from Greg KH: "Here's the big staging tree pull request for 3.19-rc1. We continued to delete more lines than were added, always a good thing, but not at a huge rate this release, only about 70k lines removed overall mostly from removing the horrid bcm driver. Lots of normal staging driver cleanups and fixes all over the place, well over a thousand of them, the shortlog shows all the horrid details. The "contentious" thing here is the movement of the Android binder code out of staging into the "real" part of the kernel. This is code that has been stable for a few years now and is working as-is in the tens of millions of devices with no issues. Yes, the code is horrid, and the userspace api leaves a lot to be desired, but it's not going to change due to legacy issues that we have no control over. Because so many devices and companies rely on this, and the code is stable, might as well promote it out of staging. This was all discussed at the Linux Plumbers conference, and everyone participating agreed that this was the best way forward. There is work happening to replace the binder code with something new that is happening right now, but I don't expect to see the results of that work for another year at the earliest. If that ever happens, and Android switches over to it, I'll gladly remove this version. As for maintainers, I'll be glad to maintain this code, I've been doing it for the past few years with no problems. I'll send a MAINTAINERS entry for it before 3.19-final is out, still need to talk to the Google developers about if they are willing to help with it or not, last I checked they were, which was good.

2013-09-08staging: iio: replace strict_strto*() with kstrto*()Jingoo Han
The usage of strict_strto*() is not preferred, because strict_strto*() is obsolete. Thus, kstrto*() should be used. Previously, there were only strict_strtol(), strict_strtoul(), strict_strtoull(), and strict_strtoll(). Thus, when converting to the variables, only long, unsigned long, unsigned long long, and long long can be used. However, kstrto*() provides various functions handling all types of variables. Therefore, the types of variables can be changed properly. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2012-09-06staging:iio:sysfs-trigger: Use irq_work to properly active triggerLars-Peter Clausen
Since iio_trigger_poll() calls generic_handle_irq() it need to be called from hardirq context. The sysfs trigger is kicked from userspace, so it is obviously not possible to fulfill this requirement by calling iio_trigger_poll directly. As a workaround commit 1f785681 ("staging:iio:trigger sysfs userspace trigger rework.") added iio_trigger_poll_chained() which uses handle_nested_irq instead of generic_handle_irq. This in itself is a hack and only works by chance. handle_nested_irq is intended to be called from the threaded interrupt handler of the parent IRQ. Using handle_nested_irq is also problematic since it will only call the threaded handler of the IRQ. But quite a few IIO drivers rely on their hardirq handler being called or undefined behaviour will occur. This patch uses the irq_work framework to schedule the call to iio_trigger_poll() from hardirq context, which fixes the issues described above.
