V4L/DVB (6707): pvrusb2: Remove use of volatile in pipeline control state machine
pvrusb2: Eliminate use of volatile in pipeline control state variables. These were all cases of paranoia; upon further review the overall mechanism employed here should not require use of volatile. This had originally been done out of paranoia, and I have since been convinced that the paranoia is not required.
