V4L/DVB (11847): saa7134: Simplify handling of IR on MSI TV@nywhere Plus
Now that we instantiate I2C IR devices explicitly, we can skip probing altogether on boards where the I2C IR device address is known. The MSI TV@nywhere Plus is one of these boards. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
