[media] media: rc: ir-sharp-decoder: add support for Denon variant of the protocol (1b0621af) · Commits · 戴 / test

Denon also uses the Sharp protocol, however with different check bits. It would have been also possible to add this as a separate protocol but this may not be worth the effort. Successfully tested with a Denon RC-1002 remote control. Signed-off-by:
