From: Hans de Goede Date: Sun, 25 Feb 2018 10:46:51 +0000 (+0100) Subject: ASoC: rt5651: Do not modify jd and PLL power bits from set_bias_level() X-Git-Tag: v4.17-rc1~119^2~1^2~19^3~17 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=887fcc6f0514380f17d5016dd8cdfc4d9a4437ee;p=linux.git ASoC: rt5651: Do not modify jd and PLL power bits from set_bias_level() rt5651_set_bias_level(BIAS_OFF) used to unconditionally clear the entire register, including the jack-detect and PLL power bits. When jack-detection support was introduced a special case for jack-detect was added which hard-codes a register value to keep both on. This commit removes the jack-detect special case, instead simply leaving these bits as is on BIAS_OFF.
