From 2c04ea1f297a9a7513ee8107cce1568c9bfc52aa Mon Sep 17 00:00:00 2001 From: Timo Wischer Date: Wed, 4 Jul 2018 15:39:49 +0200 Subject: [PATCH] pcm: rate: Add error check for snd_pcm_avail_update() Without these changes a negative error code returned by snd_pcm_avail_update() will be not handled correctly. With this patch the returned error code of snd_pcm_avail_update() will be returned by snd_pcm_rate_avail_update().
