Hi
with kernel 3.17 using a RC6 remote with a buildin nuvoton IR receiver
(not tested others, but i think its a common problem) when
pressing/releasing the same button often within 1 second there will no
release event sent. Instead we get repeat events. To get the release
event i must press the same button with a delay of ~ 1sec.
the evtest output for kernel with the difference 3.16 and 3.17 looks like
kernel 3.16

[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@xxxxxxxxxxx: rebased, added cxusb and removed bad
whitespacing]
