From 4ef2ccc2611456667ea78c6f418ce87e1fa9fac5 Mon Sep 17 00:00:00 2001 From: Trent Piepho Date: Wed, 28 Jan 2009 21:32:58 -0300 Subject: V4L/DVB (10558): bttv: norm value should be unsigned The norm value in the driver is an index into an array and the the driver doesn't allow it to be negative or otherwise invalid. It should be unsigned but wasn't in all places. Fix some structs and functions to have the norm be unsigned. Get rid of useless checks for "< 0". Most of the driver code can't handle a norm value that's out of range, so change some ">= BTTV_TVNORMS" checks to BUG_ON(). There's no point in silently ignoring invalid driver state just to crash because of it later.
