Subject[PATCH 4.1 053/127] ASoC: davinci-mcasp: Fix XDATA check in mcasp_start_tx
Date
4.1-stable review patch.  If anyone has any objections, please let me know.

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

From: Peter Ujfalusi <peter.ujfalusi@ti.com>

commit e2a0c9fa80227be5ee017b5476638829dd41cb39 upstream.

The condition for checking for XDAT being cleared was not correct.
