ALSA: core: Fix randconfig build wrt CONFIG_PROC_FS

2015-05-29T05:21:02+00:00

There are a few leftover CONFIG_PROC_FS forgotten to replace with CONFIG_SND_PROC_FS. Fixes: cd6a65036f0e ('ALSA: replace CONFIG_PROC_FS with CONFIG_SND_PROC_FS') Reported-by: Jim Davis Signed-off-by: Takashi Iwai

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: core: Build conditionally and remove superfluous ifdefs

2015-04-24T15:31:07+00:00

Minor cleanups of Makefile to build some codes conditionally so that a few ifdefs can be reduced. Acked-by: Jaroslav Kysela Signed-off-by: Takashi Iwai

ALSA: core: Don't ignore errors at creating proc files

2015-04-24T15:31:06+00:00

So far we've ignored the errors at creating proc files in many places. But they should be rather treated seriously. Also, by assuring the error handling, we can get rid of superfluous snd_info_free_entry() calls as they will be removed by the parent in the caller side. This patch fixes the missing error checks and reduces the superfluous free calls. Acked-by: Jaroslav Kysela Signed-off-by: Takashi Iwai

ALSA: seq: fill client ID in return value of pool operation

2015-04-11T07:11:19+00:00

The returned value of 'get/seq client pool' operation has zeroed value for its client ID, against requested client ID. This commit fix the bug by filling it with index value of referred client object. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: seq: Fix init order of snd_seq_device stuff

2015-03-11T11:53:52+00:00

When the sequencer driver is built in kernel, it may panic at boot because of the uninitialized snd_seq_bus_type. Initialize it properly via subsys_initcall() instead of module_init() to assure that the bus is registered beforehand.

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

2015-03-10T14:41:18+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
