[ 106/122] em28xx: regression fix: use DRX-K sync firmware requests on em28xx

[Greg Kroah-Hartman]

3.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mauro Carvalho Chehab <mchehab@xxxxxxxxxx>

commit 2425bb3d4016ed95ce83a90b53bd92c7f31091e4 upstream.

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)
