2016-05-17sound: oss: Use setup_timer and mod_timer.Muhammad Falak R Wani1-5/+3
The function setup_timer combines the initialization of a timer with the initialization of the timer's function and data fields. The mulitiline code for timer initialization is now replaced with function setup_timer. Also, quoting the mod_timer() function comment: -> mod_timer() is a more efficient way to update the expire field of an active timer (if the timer is inactive it will be activated). Use setup_timer() and mod_timer() to setup and arm a timer, making the code compact and aid readablity.

2015-12-09sound/oss: remove VIRT_TO_BUS dependencyArnd Bergmann1-1/+1
The OSS sound drivers used to rely on virt_to_bus(), but don't any more, so we can remove the Kconfig dependency. As a lot of architectures don't provide VIRT_TO_BUS any more, removing the dependency in sounds/oss/ would make the deprecated drivers appear there, which we probably don't want. Instead I'm replacing the simple dependency with 'VIRT_TO_BUS || RPC || NETWINDER' so we can still build these sound drivers for the platforms that need them, but don't change anything on other architectures. As a follow-up, we can remove the virt_to_bus() implementation and Kconfig symbol in the ARM architecture. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2015-04-18sound/oss: fix deadlock in sequencer_ioctl(SNDCTL_SEQ_OUTOFBAND)Alexey Khoroshilov1-10/+2
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.

2013-05-13sound: Fix make allmodconfig on MIPS correctlyPaul Bolle1-1/+1
Commit d4702b189c ("sound: Fix make allmodconfig on MIPS") added a (negative) dependency on ISA_DMA_SUPPORT_BROKEN. Since that Kconfig symbol doesn't exist, this dependency will always evaluate to true. Apparently GENERIC_ISA_DMA_SUPPORT_BROKEN was meant to be used here.

A significant change in the subsystem level is the introduction of snd_soc_component, which will help more generic handling of SoC and off-SoC components.

2013-05-03sound: Fix make allmodconfig on MIPSTakashi Iwai1-0/+1
The compile of soundcard.c is broken on MIPS when allmodconfig is used because of the missing MAX_DMA_CHANNELS definition. As a simple workaround, just add a Kconfig dependency.
