Tested on kernels 2.6.35, 3.0, 3.2, 3.5 & 3.7
This upstream commit and the ones in patch 2 & 3 are critical for boot
dead lock on 64 bit systems, the remaining commits bring the driver up.
staging: vt6656: [BUG] out of bound array reference in RFbSetPower.
Calling RFbSetPower with uCH zero value will cause out of bound array reference.
This causes 64 bit kernels to oops on boot.
Note: Driver does not function on 64 bit kernels and should be
blacklisted on them.
