Hello Jef,
thank you for the feedback, I'll try to send a patch set wich contains
bigger steps. I hope the separation will be not a too big step and won't
make it too difficult to bisect any possible problem I might introduce
with this change. But hope for the best and imagine the easy way when
no regression was introduced.
I am also thinking about finding the common functions which can be
compiled separately either in a helper module or to gspca_main maybe.
But first I focus on the pac7302/pac7311 separation.
