Subject: ASoC: twl6040: Shift 2 identifies the HS output in out_drv_event
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6fbb32d175368b6ab8fb827e65cd8d18ed04c1f3;p=openwrt%2Fstaging%2Fblogic.git

ASoC: twl6040: Shift 2 identifies the HS output in out_drv_event

None of the driver handled by out_drv_event have it's power
bit shifted by 3.
Remove the case for shift 3, and also add comment for the cases.
