Thank you for your contributions.

rc-core (drivers/media/rc) is in good shape and I don't know of any
outstanding issues.

There is a ton of work around dvb, but this requires actual dvb hardware
to test.

 - port drivers/media/usb/dvb-usb to drivers/media/usb/dvb-usb-v2
 - Re-write dvb frontend without dvb_attach()
 - Implement dma-buf for dvb

Like I said, you'll need actual hardware to test against, and this is
probably not beginner tasks.
