ALSA: replace CONFIG_PROC_FS with CONFIG_SND_PROC_FS

2015-05-27T19:25:19+00:00

We may disable proc fs only for sound part, to reduce ALSA memory footprint. So add CONFIG_SND_PROC_FS and replace the old CONFIG_PROC_FSs in alsa code. With sound proc fs disabled, we can save about 9KB memory size on X86_64 platform. Signed-off-by: Jie Yang Reviewed-by: Mark Brown Signed-off-by: Takashi Iwai

ALSA: seq_oss: Drop superfluous error/debug messages after malloc failures

2015-03-10T14:39:55+00:00

The kernel memory allocators already report the errors when the requested allocation fails, thus we don't need to warn it again in each caller side. Signed-off-by: Takashi Iwai

ALSA: seq: Drop snd_seq_autoload_lock() and _unlock()

2015-02-12T13:42:31+00:00

The autoload lock became already superfluous due to the recent rework of autoload code. Let's drop them now. This allows us to simplify a few codes nicely. Signed-off-by: Takashi Iwai

ALSA: seq: Define driver object in each driver

2015-02-12T13:15:54+00:00

This patch moves the driver object initialization and allocation to each driver's module init/exit code like other normal drivers. The snd_seq_driver struct is now published in seq_device.h, and each driver is responsible to define it with proper driver attributes (name, probe and remove) with snd_seq_driver specific attributes as id and argsize fields. The helper functions snd_seq_driver_register(), snd_seq_driver_unregister() and module_snd_seq_driver() are used for simplifying codes. Signed-off-by: Takashi Iwai

ALSA: seq: Deletion of unnecessary checks before the function call "snd_midi_event_free"

2015-01-04T14:11:05+00:00

The snd_midi_event_free() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Takashi Iwai

ALSA: core: Deletion of unnecessary checks before two function calls

2014-11-21T19:06:57+00:00

The functions snd_seq_oss_timer_delete() and vunmap() perform also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Takashi Iwai

ALSA: seq_oss: Use standard printk helpers

2014-02-14T07:14:18+00:00

Use the standard pr_xxx() helpers instead of home-baked snd_print*(). Signed-off-by: Takashi Iwai

ALSA: seq_oss: Drop debug prints

2014-02-14T07:14:13+00:00

The debug prints in snd-seq-oss module are rather useless. Let's clean up before further modifications. Signed-off-by: Takashi Iwai

ALSA: Drop unused name argument in snd_register_oss_device()

2014-02-12T09:58:19+00:00

The last argument, name, of snd_oss_register_device() is nowhere referred in the function in the current code. Let's drop it. Signed-off-by: Takashi Iwai

ALSA: seq-oss: Initialize MIDI clients asynchronously

2013-07-17T07:19:24+00:00

We've got bug reports that the module loading stuck on Debian system with 3.10 kernel. The debugging session revealed that the initial registration of OSS sequencer clients stuck at module loading time, which involves again with request_module() at the init phase. This is triggered only by special --install stuff Debian is using, but it's still not good to have such loops. As a workaround, call the registration part asynchronously. This is a better approach irrespective of the hang fix, in anyway. Reported-and-tested-by: Philipp Matthias Hahn Cc: Signed-off-by: Takashi Iwai
