V4L/DVB (7939): pvrusb2: Remove sysfs interface hackery
Back in the early days of the pvrusb2 driver, the kernel class mechanism in use for the sysfs interface had no means to pass per-attribute information to the show / store functions. This forced me to implement a horrible ugly thunking mechanism (i.e. infer the missing data through the use of dedicated cookie cutter bounce functions). However now we're using a better mechanism which also passes enough additional information to the show / store functions that we no longer need the hack. So eliminate all the crap. Yay!
