sound: oss/sb_audio: use swap() in sb_audio_close()

Use kernel.h macro definition. Thanks to Julia Lawall for Coccinelle scripting support. Signed-off-by: Fabian Frederick Signed-off-by: Takashi Iwai

sound/oss: use schedule_timeout_interruptible()

2015-05-29T15:26:32+00:00

API consolidation with coccinelle found: ./sound/oss/msnd_pinnacle.c:1292:2-18: consolidation with schedule_timeout_*() recommended This is a 1:1 conversion of the current calls to an available helper only - so only an API consolidation to improve readability. Patch was compile tested with x86_64_defconfig Patch is against 4.1-rc5 (localversion-next is -next-20150529) Signed-off-by: Nicholas Mc Guire Signed-off-by: Takashi Iwai

sound: oss: fix build warning

2015-05-18T08:27:17+00:00

while building with allyesconfig it was giving a build warning about unused variable. declare the variable only if the driver is built as a module. Signed-off-by: Sudip Mukherjee Signed-off-by: Takashi Iwai

sound/oss: fix deadlock in sequencer_ioctl(SNDCTL_SEQ_OUTOFBAND)

2015-04-18T07:05:55+00:00

A deadlock can be initiated by userspace via ioctl(SNDCTL_SEQ_OUTOFBAND) on /dev/sequencer with TMR_ECHO midi event. In this case the control flow is: sound_ioctl() -> case SND_DEV_SEQ: case SND_DEV_SEQ2: sequencer_ioctl() -> case SNDCTL_SEQ_OUTOFBAND: spin_lock_irqsave(&lock,flags); play_event(); -> case EV_TIMING: seq_timing_event() -> case TMR_ECHO: seq_copy_to_input() -> spin_lock_irqsave(&lock,flags); It seems that spin_lock_irqsave() around play_event() is not necessary, because the only other call location in seq_startplay() makes the call without acquiring spinlock. So, the patch just removes spinlocks around play_event(). By the way, it removes unreachable code in seq_timing_event(), since (seq_mode == SEQ_2) case is handled in the beginning. Compile tested only. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by: Alexey Khoroshilov Signed-off-by: Takashi Iwai

sound: Deparenthesize negative error returns

2015-03-24T10:41:37+00:00

Make the returns a bit more kernel standard style. Signed-off-by: Joe Perches Signed-off-by: Takashi Iwai

sound/sb_midi: a couple indenting fixes

2015-02-25T19:08:27+00:00

Let's make things line up a little bit better. Signed-off-by: Dan Carpenter Signed-off-by: Takashi Iwai

sound/sb_ess: white space cleanups

2015-02-25T19:08:21+00:00

These weren't aligned on the same lines as the surrounding code and the printk was quite messy. Signed-off-by: Dan Carpenter Signed-off-by: Takashi Iwai

sound/oss/opl3: remove some stray whitespace

2015-02-25T19:08:15+00:00

Removed an extra tab and a extra space character. Signed-off-by: Dan Carpenter Signed-off-by: Takashi Iwai

sound: sys_timer: indent poll_def_tmr() correctly

2015-02-25T19:08:07+00:00

The indenting here was really whacky and not consistent from one line to the next. I also reverse the "if (opened)" and "if (tmr_running)" tests so that I could remove two indent levels. Signed-off-by: Dan Carpenter Signed-off-by: Takashi Iwai

Pull sound updates from Takashi Iwai: "In this batch, you can find lots of cleanups through the whole subsystem, as our good New Year's resolution. Lots of LOCs and commits are about LINE6 driver that was promoted finally from staging tree, and as usual, there've been widely spread ASoC changes. Here some highlights: ALSA core changes - Embedding struct device into ALSA core structures - sequencer core cleanups / fixes - PCM msbits constraints cleanups / fixes - New SNDRV_PCM_TRIGGER_DRAIN command - PCM kerneldoc fixes, header cleanups - PCM code cleanups using more standard codes - Control notification ID fixes Driver cleanups - Cleanups of PCI PM callbacks - Timer helper usages cleanups - Simplification (e.g. argument reduction) of many driver codes HD-audio - Hotkey and LED support on HP laptops with Realtek codecs - Dock station support on HP laptops - Toshiba Satellite S50D fixup - Enhanced wallclock timestamp handling for HD-audio - Componentization to simplify the linkage between i915 and hd-audio drivers for Intel HDMI/DP USB-audio - Akai MPC Element support - Enhanced timestamp handling ASoC - Lots of refactoringin ASoC core, moving drivers to more data driven initialization and rationalizing a lot of DAPM usage - Much improved handling of CDCLK clocks on Samsung I2S controllers - Lots of driver specific cleanups and feature improvements - CODEC support for TI PCM514x and TLV320AIC3104 devices - Board support for Tegra systems with Realtek RT5677 - New driver for Maxim max98357a - More enhancements / fixes for Intel SST driver Others - Promotion of LINE6 driver from staging along with lots of rewrites and cleanups - DT support for old non-ASoC atmel driver - oxygen cleanups, XIO2001 init, Studio Evolution SE6x support - Emu8000 DRAM size detection fix on ISA(!!)
