From b43fccf4b5cae58829abbeae497a98505fa1a5e9 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Sun, 14 Jun 2015 10:28:01 +0800 Subject: [PATCH] ASoC: ml26124: Remove duplicate code Current code has duplicate code for 16000, 32000 and 48000 sample rates. get_srate() returns negative error code for unsupported rate, so we can remove the duplicate code in the swith cases by calling get_srate() first.
