Subject: V4L/DVB (11848): saa7134: Simplify handling of IR on AVerMedia Cardbus E506R
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d9a88e632b2c527165434c404a0a1ca16d2d3793;p=linux-beck.git

V4L/DVB (11848): saa7134: Simplify handling of IR on AVerMedia Cardbus E506R

Now that we instantiate I2C IR devices explicitly, we can skip probing
altogether on boards where the I2C IR device address is known. The
AVerMedia Cardbus E506R is one of these boards.
