V4L/DVB: bttv: Move I2C IR initialization
Move I2C IR initialization from just after I2C bus setup to right before non-I2C IR initialization. This avoids the case where an I2C IR device is blocking audio support (at least the PV951 suffers from this). It is also more logical to group IR support together, regardless of the connectivity. This fixes bug #15184: http://bugzilla.kernel.org/show_bug.cgi?id=15184 Signed-off-by: Jean Delvare <khali@linux-fr.org> CC: stable@kernel.org Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
