Subject: [PATCH] staging: comedi: comedi_fops: remove disabled subdevice
 lock/unlock callback

According to Ian Abbott, this code was added in comedi-0.7.6 back in June 1999
and has always been disabled.

The 'lock_f' and 'unlock' members don't even exist in the comedi_subdevice.
Just remove the disabled code.
