From a747db239010bcabe48e3429556b782988a11797 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 9 Dec 2019 10:49:17 +0100 Subject: [PATCH] ALSA: lx6464es: Use managed buffer allocation 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.
