[media] mceusb: add a per-model structure
The previous logic needed duplicate USB table structs, one to store the list of the devices, and 3 sets of other structs, to store the quirks list. With this change, devices that require expecial quirks just need to have a .driver_info = <quirk entry>. It also allows adding some extra quirks, like per-model RC tables. As a bonus, this patch reduced in 10% the data segment size: text data bss dec hex filename 15487 5008 4 20499 5013 old/mceusb.ko 15438 4496 4 19938 4de2 new/mceusb.ko Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Jarod Wilson <jarod@redhat.com>
