From 6f9b33123cc1a4bc3f0069be6f0cb7f325ee2fbd Mon Sep 17 00:00:00 2001 From: Frank Schäfer Date: Sun, 23 Sep 2012 10:29:42 -0300 Subject: [media] gspca_pac7302: correct register documentation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit R,G,B balance registers are 0x01-0x03 instead of 0x02-0x04, which lead to the wrong conclusion that values are inverted. Exposure is controlled via page 3 registers and this is already documented. Also fix a whitespace issue.
