[PATCH 3/4] media: dvb/af9015, refactor remote setting
From: Jiri Slaby
Date: Fri Jan 22 2010 - 10:11:35 EST
Add af9015_setup structure to hold (right now only remote) setup
of distinct receivers.
Add af9015_setup_match for matching ids against tables.
This is for easier matching different kind of ids against tables
to obtain setups. Currently module parameters and usb vendor ids
are switched into and matched against tables. Hashes will follow.
