Subject: [PATCH] ALSA: au88x0: Use managed buffer allocation
Git-commit: 8c847a423572e816629f67bea2e13717b3470409
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.
