The pvrusb2 driver already should not require the BKL.  Though since 
this driver (like every V4L driver) is using video_usercopy() then it's 
obviously going along for the ride here with respect to the overall 
issue here in pushing the lock down into video_usercopy().  In the mean 
time, for the pvrusb2 portion of this patch...
