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. Signed-off-by: Malcolm Priestley <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
