From 09e263cd4a1d16f12e5bca8a5575ed2a2dddbf11 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 9 Dec 2019 10:49:14 +0100 Subject: [PATCH] ALSA: ice1724: 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.
