ALSA: firewire: Convert to the common vmalloc memalloc

2019-11-06T14:47:42+00:00

The recent change (*) in the ALSA memalloc core allows us to drop the special vmalloc-specific allocation and page handling. This patch coverts to the common code.

ALSA: isight: fix leak of reference to firewire unit in error path of .probe callback

2018-10-12T06:08:04+00:00

In some error paths, reference count of firewire unit is not decreased. This commit fixes the bug. Fixes: 5b14ec25a79b('ALSA: firewire: release reference count of firewire unit in .remove callback of bus driver') Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: firewire: release reference count of firewire unit in .remove callback of bus driver

2018-10-10T10:11:41+00:00

In a previous commit, drivers in ALSA firewire stack blocks .remove callback of bus driver. This enables to release members of private data in the callback after releasing device of sound card. This commit simplifies codes to release the members. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: firewire: block .remove callback of bus driver till all of ALSA character devices are released

2018-10-10T10:11:34+00:00

At present, in .remove callback of bus driver just decrease reference count of device for ALSA card instance. This delegates release of the device to a process in which the last of ALSA character device is released. On the other hand, the other drivers such as for devices on PCIe are programmed to block .remove callback of bus driver till all of ALSA character devices are released. For consistency of behaviour for whole drivers, this probably confuses users. This commit takes drivers in ALSA firewire stack to imitate the above behaviour.

ALSA: pcm: Nuke snd_pcm_lib_mmap_vmalloc()

2018-07-18T06:24:29+00:00

snd_pcm_lib_mmap_vmalloc() was supposed to be implemented with somewhat special for vmalloc handling, but in the end, this turned to just the default handler, i.e. NULL. As the situation has never changed over decades, let's rip it off. Reviewed-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

locking/atomics: COCCINELLE/treewide: Convert trivial ACCESS_ONCE() patterns to READ_ONCE()/WRITE_ONCE()

2017-10-25T09:01:08+00:00

Please do not apply this to mainline directly, instead please re-run the coccinelle script shown below and apply its output. For several reasons, it is desirable to use {READ,WRITE}_ONCE() in preference to ACCESS_ONCE(), and new code is expected to use one of the former. So far, there's been no reason to change most existing uses of ACCESS_ONCE(), as these aren't harmful, and changing them results in churn. However, for some features, the read/write distinction is critical to correct operation. To distinguish these cases, separate read/write accessors must be used. This patch migrates (most) remaining ACCESS_ONCE() instances to {READ,WRITE}_ONCE(), using the following coccinelle script: ---- // Convert trivial ACCESS_ONCE() uses to equivalent READ_ONCE() and // WRITE_ONCE() // $ make coccicheck COCCI=/home/mark/once.cocci SPFLAGS="--include-headers" MODE=patch virtual patch @ depends on patch @ expression E1, E2; @@ - ACCESS_ONCE(E1) = E2 + WRITE_ONCE(E1, E2) @ depends on patch @ expression E; @@ - ACCESS_ONCE(E) + READ_ONCE(E) ---- Signed-off-by: Mark Rutland Signed-off-by: Paul E.

Add a new helper function snd_pcm_stop_xrun() to the standard sequnce lock/snd_pcm_stop(XRUN)/unlock by a single call, and replace the existing open codes with this helper. The function checks the PCM running state to prevent setting the wrong state, too, for more safety. Signed-off-by: Takashi Iwai
