[alsa-devel] [PATCH for-5.6 00/14] media: ALSA PCM API updates

[Takashi Iwai]

Hi,

this is a patch set to adapt the latest ALSA PCM API to media
drivers.  Basically these are merely cleanups, as shown in diffstat,
and there should be no functional changes.

As the corresponding ALSA PCM API change is found in 5.5-rc1, please
apply these on 5.5-rc1 or later.  Or if you prefer, I can merge them
through sound tree, too.  Let me know.


thanks,

Takashi

[alsa-devel] [PATCH for-5.6 01/14] media: solo6x10: Use managed buffer allocation

[Takashi Iwai]

Clean up the driver with the new managed buffer allocation API.
The hw_params and hw_free callbacks became superfluous and dropped.

[alsa-devel] [PATCH for-5.6 11/14] media: cobalt: Drop superfluous ioctl PCM ops

[Takashi Iwai]

snd_cobalt_pcm_ioctl() does nothing but calling the default handler.
Now PCM core accepts NULL as the default ioctl ops, so let's drop
altogether.

PCM core deals the empty ioctl field now as default.
Let's kill the redundant lines.
