From: Yegor Yefremov Date: Thu, 4 Apr 2013 14:13:20 +0000 (+0200) Subject: ASoC: davinci-mcasp: don't overwrite DIT settings X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f5023af65a9bdd586b33b56e83f1eb3529292991;p=linux-beck.git ASoC: davinci-mcasp: don't overwrite DIT settings Channel size settings will be made at the end of davinci_mcasp_hw_params() routine and thus overwrite frame format settings made for DIT mode. This patch fixes this issue by taking op_mode into account. Tested with official PSP 3.2 kernel and sii9022a HDMI transmitter.
