I've added this patch earlier today on my tree:

http://git.linuxtv.org/media_tree.git?a=commit;h=3a057c36346f60bd0fb4fe7d7a68c4d931d8768f

and the other IR_CORE fixup at staging/tm6000:
http://git.linuxtv.org/media_tree.git?a=commit;h=926a2496438f44268130f72f5e102dcac484573d

I'll be sending them today to my linux-next tree and likely tomorrow to upstream,
together with a few other fixes.
