[alsa-devel] [PATCH for-5.6 0/2] drm/bridge: dw-hdmi: PCM API updates

[Takashi Iwai]

Hi,

this is a patch set for updating ALSA PCM API usages in dw-hdmi
driver.  I already tried to "fix" the driver some time ago but it was
utterly wrong.  So this is a combination of the revised patch and
another cleanup patch.

The first one is to change the buffer allocation mechanism in the
driver to the manual allocation of the h/w buffer and the automatic
allocation of PCM stream buffers via the new standard API.  The
significant change is that size of the h/w buffer isn't no longer
controlled via ALSA preallocation proc file but rather via the new
module option (if any).

The second one is a oneliner patch just to remove the superfluous PCM
ops.

Both need the ALSA PCM core changes in 5.5-rc1, so please apply them
on top of 5.5-rc1 or later.  Or, just let me know if I should apply
them through sound git tree.


thanks,

Takashi
