[PATCH 09/10] mfd: wm8400-core: Supply description for wm8400_reset_codec_reg_cache's arg

[Lee Jones]

Kerneldoc syntax is used, but not complete.  Descriptions required.

Prevents warnings like:

 drivers/mfd/wm8400-core.c:113: warning: Function parameter or member 'wm8400' not described in 'wm8400_reset_codec_reg_cache'
