enable_req_count is only ever accessed inside the spinlock, so to avoid confusion that there are concurrent accesses and simplify the code, change it to an int. One access outside of the spinlock is in enable_show() which appears to allow partially written data to be displayed between enable_req_count, powered and enabled so move this one inside the spin lock too.
