Subject: [PATCH] ALSA: pcsp: Use managed buffer allocation
Git-commit: d635f09e919e6ea9214a7676e26ef6755b3453a0
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() are dropped.
