3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: =?UTF-8?q?Eric=20B=C3=A9nard?= <[email protected]> commit e875c1e3e758447ba81ca450d89434b3b0496d37 upstream. * commit f9dfbf9 "ASoC: tlv320aic23: convert to soc-cache" leads to a bug preventing resumeof the codec as regmap expects a 9 bits data register but 0xFFFF is passed in tlv320aic23_set_bias_level and this values gets cached preventing any write to the TLV320AIC23_PWR register as the final value produced by regmap is (register << 9) | value * this patch solves the problem by only working on the 9 bits the register contains.
