Subject: [PATCH] ALSA: riptide: Use managed buffer allocation
Git-commit: 0dd323695c7b8dc33c6dc2d23bbe99a8ecd5d627
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.
