This adds device tree support for the AC97 controller. It uses the soc-ac97link bindings, but actually only ac97-reset is used. Signed-off-by:

The iounmap() function performs 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:

Remove function declarations for functions that don't have a matching implementation. For snd_pcm_build_linear_format the implementation was removed in 64d27f96 ("[ALSA] Support 3-bytes 24bit format in PCM OSS emulation"). All the others never had one (as far as git history goes). Signed-off-by:

The ALSA core takes care that all preallocated memory is freed when the card (and the PCM) itself is freed. There is no need to do this manually in the driver. Signed-off-by:

The various PCM allocation functions in this driver take a pointer to a pointer of a PCM where if this parameter is provided the newly allocated PCM is stored. All callers pass NULL though, so remove the parameter. This makes the code a bit shorter and cleaner. Signed-off-by:

Most callers of snd_wss_pcm(), snd_wss_timer() and snd_cs4236_pcm() pass NULL as the last parameter, some callers pass a pointer but never use it after the function has been called and only a few callers pass a pointer and actually use it. The later is only the case for snd_wss_pcm() for snd_cs4236_pcm() and it is possible to get the same PCM object by accessing the pcm field of the snd_wss struct that was passed as the first parameter. This function removes the last parameters from the functions mentioned above and updates the callers which used it to use chip->pcm instead. This allows us to slightly simplify the functions since they don't have to check and set the last parameter anymore which makes the code slightly shorter and cleaner. Signed-off-by:

snd_es1688_pcm() takes a pointer to a pointer of a PCM where if this parameter is provided the newly allocated PCM is stored. This PCM is also available from the pcm field of the snd_es1688 struct that got passed to the same function. This patch updates all callers which passed a pointer to use that field instead and then removes the parameter from the function. This makes the code a bit shorter and cleaner. Signed-off-by:

__fls has the same semantics as ld2, so there is no need to re-implement it. Furthermore a lot of architectures have custom implementations of __fls that are able to use special hardware instructions to compute the result. This makes the code slightly shorter and faster. Signed-off-by:
