Subject: [PATCH] ALSA: atiixp: Use managed buffer allocation
Git-commit: 801bf05747642fcc1039efaf5f00d36ed52d9dd5
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518

Clean up the drivers with the new managed buffer allocation API.
The superfluous snd_pcm_lib_malloc_pages() and
snd_pcm_lib_free_pages() calls are dropped.
