ALSA: ak4114: remove redundant check on err being < 0

2016-07-12T10:28:04+00:00

snd_ak4114_create checks if the error return err is less than zero or not. This is a redundant check, err can only be < 0 to get to the __fail label, in which case just return err and remove the redundant check (since we never return -EIO). Signed-off-by: Colin Ian King Signed-off-by: Takashi Iwai

ALSA: i2c: constify snd_i2c_ops structures

2015-11-30T10:40:08+00:00

The snd_i2c_ops structures are never modified, so declare them as const. Done with the help of Coccinelle. Signed-off-by: Julia Lawall Signed-off-by: Takashi Iwai

ALSA: ak4xxx-adda: Drop unnecessary ifdef CONFIG_PROC_FS

ALSA: ak411x: simplify snd_ak4113_create() a bit

2015-03-23T12:58:59+00:00

"err" is always a negative error code here, so there is no point in checking. Removing the check silences a static checker warning and makes the code a bit more clear. Also we don't need to initialize "err". Signed-off-by: Dan Carpenter Signed-off-by: Takashi Iwai

ALSA: ak411x: Fix race of reinit() calls

2015-01-28T21:30:18+00:00

Protect the call with a mutex, as this may be called in parallel (either from the PCM rate change and the clock change). Acked-by: Jaroslav Kysela Tested-by: Pavel Hofman Signed-off-by: Takashi Iwai

ALSA: ak411x: Add PM helper functions

2015-01-28T21:30:12+00:00

Define snd_ak4114_suspend() and snd_ak4114_resume() functions to handle PM properly, stopping and restarting the work at PM. Currently only ice1712/juli.c deals with the PM and ak4114, so fix the calls there appropriately. The same PM functions are defined in ak4113.c, too, although they aren't currently called yet (ice1712/quartet.c may be enhanced to support PM later).

ALSA: ak411x: Fix stall in work callback

2015-01-28T21:29:20+00:00

When ak4114 work calls its callback and the callback invokes ak4114_reinit(), it stalls due to flush_delayed_work(). For avoiding this, control the reentrance by introducing a refcount. Also flush_delayed_work() is replaced with cancel_delayed_work_sync(). The exactly same bug is present in ak4113.c and fixed as well.
