Subject[PATCH 4.9 008/129] media: tvp5150: fix switch exit in set control handler
Date
From: Marco Felsch <m.felsch@pengutronix.de>

commit 2d29bcc8c237874795175b2930fa9a45a115175a upstream.

The function only consists of a single switch case block without a
default case. Unsupported control requests are indicated by the -EINVAL
return code trough the last return statement at the end of the function. So
exiting just the switch case block returns the -EINVAL error code but the
hue control is supported and a zero should be returned instead.

Replace the break by a 'return 0' to fix this behaviour.

Fixes: d183e4efcae8 ("[media] v4l: tvp5150: Add missing break in set
control handler")
