2014-12-15Merge tag 'driver-core-3.19-rc1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core update from Greg KH: "Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes. Everything has been in linux-next for a while" * tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (324 commits) Revert "ath: ath9k: use debugfs_create_devm_seqfile() helper for seq_file entries" fs: debugfs: add forward declaration for struct device type firmware class: Deletion of an unnecessary check before the function call "vunmap" firmware loader: fix hung task warning dump devcoredump: provide a one-way disable function device: Add dev_<level>_once variants ath: ath9k: use debugfs_create_devm_seqfile() helper for seq_file entries ath: use seq_file api for ath9k debugfs files debugfs: add helper function to create device related seq_file drivers/base: cacheinfo: remove noisy error boot message Revert "core: platform: add warning if driver has no owner" drivers: base: support cpu cache information interface to userspace via sysfs drivers: base: add cpu_device_create to support per-cpu devices topology: replace custom attribute macros with standard DEVICE_ATTR* cpumask: factor out show_cpumap into separate helper function driver core: Fix unbalanced device reference in drivers_probe driver core: fix race with userland in device_add() sysfs/kernfs: make read requests on pre-alloc files use the buffer. sysfs/kernfs: allow attributes to request write buffer be pre-allocated. fs: sysfs: return EGBIG on write if offset is larger than file size ...
2014-12-05ALSA: atmel_abdac: Add missing clock prepareAlexander Stein
Clocks must be prepared before enabling them. Do this in one step. Replace clk_enable with clk_prepare_enable and clk_disable with clk_disable_unprepare. Signed-off-by: Alexander Stein <alexanders83@web.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-10-20ALSA: atmel: drop owner assignment from platform_driversWolfram Sang
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2014-10-15dmaengine: dw: split dma-dw.h to platform and private partsAndy Shevchenko
The introduced include/linux/dma/dw.h is going to contain the private extensions and structures which are shared for dw_dmac users in the kernel. Meanwhile include/linux/platform_data/dma-dw.h keeps only platform related data types and definitions.

2014-09-11dmaengine: dw: move dw_dmac.h to where it belongs toAndy Shevchenko
There is a common storage for platform data related structures and definitions inside kernel source tree. The patch moves file from include/linux to include/linux/platform_data and renames it acoordingly. The users are also updated.

2013-12-10ALSA: atmel_abdac: clk_round_rate() can return a zero upon errorPaul Walmsley
Treat both negative and zero return values from clk_round_rate() as errors. This is needed since subsequent patches will convert clk_round_rate()'s return value to be an unsigned type, rather than a signed type, since some clock sources can generate rates higher than (2^31)-1 Hz. Eventually, when calling clk_round_rate(), only a return value of zero will be considered a error; all other values will be considered valid rates. The comparison against values less than 0 is kept to preserve the correct behavior in the meantime.

2013-12-02ALSA: atmel: Fix possible array overflowTakashi Iwai
The static checker found a possible array overflow in atmel/abdac.c: static checker warning: "sound/atmel/abdac.c:373 set_sample_rates() error: buffer overflow 'dac->rates' 6 <= 6" This patch papers over the buggy point, by ensuring that dac->rates[] update not overflowing the actual array size.

2013-05-03ALSA: atmel: Remove redundant platform_set_drvdata()Sachin Kamat
Commit 0998d06310 (device-core: Ensure drvdata = NULL when no driver is bound) removes the need to set driver data field to NULL.

2012-12-07ALSA: atmel: remove __dev* attributesBill Pemberton
CONFIG_HOTPLUG is going away as an option. As result the __dev* markings will be going away. Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit. Signed-off-by: Bill Pemberton <wfp5p@virginia.edu> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-08-20ALSA: sound/atmel/abdac.c: fix error return codeJulia Lawall
Initialize retval before returning from a failed call to ioremap. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-08-09ALSA: platform: Check CONFIG_PM_SLEEP instead of CONFIG_PMTakashi Iwai
When CONFIG_PM is set but CONFIG_PM_SLEEP is unset, SIMPLE_DEV_PM_OPS() ignores the given functions, and this leads to compile warnings. For avoiding this, simply check CONFIG_PM_SLEEP instead of CONFIG_PM. Reported-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-02-05ALSA: Add ALSA driver for Atmel Audio Bitstream DACHans-Christian Egtvedt
This patch adds ALSA support for the Audio Bistream DAC found on Atmel AVR32 devices. The ABDAC is an Atmel IP which might show up on AT91 devices in the future, hence making a generic driver which can be utilized by AT91 arch if needed. Datasheet describing the ABDAC peripheral is available in the AT32AP7000 datasheet, http://www.atmel.com/dyn/products/datasheets.asp?family_id=682 Tested on ATSTK1006 + ATSTK1000 with a class D amplifier stage.
