From e4cc4fcc7b85ec32f05343b02229492c06baba1a Mon Sep 17 00:00:00 2001

Subject: [PATCH] V4L/DVB (11411): gspca - m5602: Rework v4l ctrl handling in
 all sensors
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously, all sensors allocated a part of a large ctrl vector.
Define this vector separately for each sensor instead.
