From 74c519cb6c5f23574a4d1d4a71b2b481a7482c85 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 12 May 2010 07:01:53 -0300 Subject: [PATCH] V4L/DVB: gspca_tv8532: rename brightness control to exposure What we've called brightness so far actually is an exposure control, rename it and fixup the maximum and default values.
