From: Hans Verkuil Date: Sun, 29 Mar 2009 20:47:30 +0000 (-0300) Subject: V4L/DVB (11305): cx88: prevent probing rtc and ir devices X-Git-Url: http://www.pilppa.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=43d5eab7d632de5bde582d41b5d0eac01b52bb3a;p=linux-2.6-omap-h63xx.git V4L/DVB (11305): cx88: prevent probing rtc and ir devices tuner-core.c contains a hack for cx88 board to prevent probing of certain addresses: /* HACK: Ignore 0x6b and 0x6f on cx88 boards. * FusionHDTV5 RT Gold has an ir receiver at 0x6b * and an RTC at 0x6f which can get corrupted if probed. */ With the new i2c API this hack no longer works. So instead change the list of tuner probe addresses in the cx88 driver itself, which is much more clean.
