Subject: [PATCH] ALSA: mixart: Use managed buffer allocation
Git-commit: c6312f3926d77d9f5e8aaf1fc5dc7eca6b42f131
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518
Clean up the driver with the new managed buffer allocation API.
The superfluous snd_pcm_lib_malloc_pages() and
snd_pcm_lib_free_pages() calls are dropped.
