[alsa-devel] [PATCH 1/2] ASoC: wm8580: Fix build error

[Sachin Kamat]

Re-organize the code a bit to fix the following build errors and warnings:

sound/soc/codecs/wm8580.c:932:21: error: variable ‘wm8580_regmap’ has initializer but incomplete type
 static const struct regmap_config wm8580_regmap = {

sound/soc/codecs/wm8580.c:233:20: warning: ‘wm8580_supply_names’ defined but not used [-Wunused-variable]
sound/soc/codecs/wm8580.c:840:34: warning: ‘wm8580_dai’ defined but not used [-Wunused-variable]
sound/soc/codecs/wm8580.c:914:36: warning: ‘soc_codec_dev_wm8580’ defined but not used [-Wunused-variable]
