From 05a1c88d9b8dd344edfce3eaa00a3cac866cf3ad Mon Sep 17 00:00:00 2001
From: Dave Stevenson <dave.stevenson@raspberrypi.com>

Subject: [PATCH] media: i2c: ov5647: Neither analogue gain nor
exposure need EXECUTE_ON_WRITE
The controls for analogue gain and exposure were defined with
V4L2_CTRL_FLAG_EXECUTE_ON_WRITE. This is not required as we only need
to send changes to the sensor.
