3.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jianqun <jay...@rock-chips.com>
commit 29f95bd76f6ec1eff88eec6a04191104a11a7f97 upstream.
We can get into an infinite loop if the I2S_CLR register fails to
clear due to a missing break statement, so add that.
