From 8c847a423572e816629f67bea2e13717b3470409 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 9 Dec 2019 10:48:57 +0100 Subject: [PATCH] ALSA: au88x0: Use managed buffer allocation 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.
