[PATCH 0/2] ALSA/DRM: vmalloc PCM buffer helper cleanup

[Takashi Iwai <tiwai@suse.de>]

Hi,

we still keep the legacy vmalloc ALSA PCM helper API since there is
only a single user of it, namely, the DRM dw-hdmi bridge driver.
In the past, I attempted to change the buffer management of the
driver, but due to the lack of testing, it failed to get merged:
  https://lore.kernel.org/20191210154536.29819-1-tiwai@suse.de

So, this is a second try after some years of gap: now the relevant
code snippet is moved from ALSA core to dw-hdmi driver itself, and the
API functions are dropped.  There should be no functional changes in
the driver.

If DRM people don't mind and give an ack, I can take the change for
dw-hdmi code together with ALSA core code drop via sound tree for
6.12.


thanks,

Takashi
