Subject: [PATCH] ASoC: twl6040: make pointer dmic_codec_dev static

From: Colin Ian King <colin.king@...onical.com>

The pointer dmic_codec_dev is local to the source and does not need
to be in global scope, so make it static.

Cleans up sparse warning:
warning: symbol 'dmic_codec_dev' was not declared. Should it be static?
