Subject: [PATCH 3.16 071/129] ASoC: fsl_esai: fix register setting issue
 in RIGHT_J mode

3.16.70-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: "S.j. Wang" <shengjiu.wang@....com>

commit cc29ea007347f39f4c5a4d27b0b555955a0277f9 upstream.

The ESAI_xCR_xWA is xCR's bit, not the xCCR's bit, driver set it to
wrong register, correct it.
