[media] rc-core: document the protocol type
Right now the protocol information is not preserved, rc-core gets handed a scancode but has no idea which protocol it corresponds to. This patch (which required reading through the source/keymap for all drivers, not fun) makes the protocol information explicit which is important documentation and makes it easier to e.g. support multiple protocols with one decoder (think rc5 and rc-streamzap). The information isn't used yet so there should be no functional changes. [m.chehab@samsung.com: rebased, added cxusb and removed bad whitespacing] Signed-off-by: David Härdeman <david@hardeman.nu> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
