From a1606102dafe6942905e97a88ceea9a60e1a2c7d Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 21 May 2014 19:00:05 -0300 Subject: [PATCH] [media] v4l: vsp1: sru: Fix the intensity control default value The default value isn't set and defaults to 0, which isn't in the 1-6 min-max range. Fix it by setting the default value to 1. This shoud have been caught when checking the control handler error field at initialization time, but the check was missing. Add it.
