Subject: ASoC: wm9081: Use devm_regmap_init_i2c()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a5710c0135db75f1c97c31e835f37d1e94096346;p=linux-beck.git

ASoC: wm9081: Use devm_regmap_init_i2c()

devm_regmap_init_i2c() is device managed and makes error
handling and code cleanup simpler.
