From 66b3621b8b6f3e184b5dd34358de41bcd5a73bb5 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 10 Dec 2019 15:26:08 +0100 Subject: [PATCH] ASoC: cros_ec_codec: 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.
