+Subject: [PATCH 148/165] ASoC: tlv312aic23: unbreak resume
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+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.
