From a1dec5160d6e536b409761c1914500f4a7cf08c2 Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Fri, 24 Aug 2007 01:13:07 -0300 Subject: [PATCH] V4L/DVB (6180): tuner: don't probe 0x6b or 0x6f on cx88 boards Ignore 0x6b and 0x6f on cx88 boards. Some FusionHDTV cards have an ir receiver at 0x6b and an RTC at 0x6f which can get corrupted if probed.
