em28xx: regression fix: use DRX-K sync firmware requests on em28xx
As em28xx-dvb will always be initialized asynchronously, there's no need anymore for a separate thread to load the DRX-K firmware. Fixes a known regression with kernel 3.6 with tda18271 driver and asynchronous DRX-K firmware load. Antti tested it with the following hardware: Hauppauge WinTV HVR 930C MaxMedia UB425-TC PCTV QuatroStick nano (520e) Tested-by: Antti Palosaari <crope@iki.fi> Cc: stable@kernel.org # for Kernel 3.6 - please note that driver location has changed Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
