9 | commit e875c1e3e758447ba81ca450d89434b3b0496d37 upstream. | ||
10 | |||
11 | * commit f9dfbf9 "ASoC: tlv320aic23: convert to soc-cache" leads to | ||
12 | a bug preventing resumeof the codec as regmap expects a 9 bits data | ||
13 | register but 0xFFFF is passed in tlv320aic23_set_bias_level and this | ||
14 | values gets cached preventing any write to the TLV320AIC23_PWR | ||
15 | register as the final value produced by regmap is (register << 9) | value | ||
16 | |||
17 | * this patch solves the problem by only working on the 9 bits the | ||
18 | register contains. | ||
