in a product). The button is wired to pin 56 on the em2880.

A number of V4L drivers have a mod param to specify their preferred minors.
This is because it is often desirable for applications to have a static /dev

1) the requested minor may already be taken
2) using a mod param is driver specific
3) it requires every driver to add a param
4) requires configuration by hand

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!
