Subject: [PATCH 22/34] [media] DaVinci-VPFE-Capture: Move two assignments in
 vpfe_s_input()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 12 Oct 2016 11:22:23 +0200

Move assignments for two local variables into an else branch so that
their setting will only be performed after corresponding data processing
succeeded by this function.
