35a246363e drivers/media: Add export.h for EXPORT_SYMBOL/THIS_MODULE as required
These two macros were in module.h but now module.h is no longer
sprayed across every source file imaginable, so the users need
to expicitly call out their use of them.

f5f2cc646a [media] rc-core support for Microsoft IR keyboard/mouse
This is a custom IR protocol decoder, for the RC-6-ish protocol used by
the Microsoft Remote Keyboard, apparently developed internally at
Microsoft, and officially dubbed MCIR-2, per their March 2011 remote and
transceiver requirements and specifications document, which also touches
on this IR keyboard/mouse device.

Its a standard keyboard with embedded thumb stick mouse pointer and
mouse buttons, along with a number of media keys. The media keys are
standard RC-6, identical to the signals from the stock MCE remotes, and
will be handled as such. The keyboard and mouse signals will be decoded
and delivered to the system by an input device registered specifically
by this driver.

Successfully tested with multiple mceusb-driven transceivers, as well as
with fintek-cir and redrat3 hardware. Essentially, any raw IR hardware
with enough sampling resolution should be able to use this decoder,
nothing about it is at all receiver-hardware-specific.

This work is inspired by lirc_mod_mce:

The documentation there and code aided in understanding and decoding the
protocol, but the bulk of the code is actually borrowed more from the
existing in-kernel decoders than anything. I did recycle the keyboard
keycode table, a few defines, and some of the keyboard and mouse data
parsing bits from lirc_mod_mce though.

Special thanks to James Meyer for providing the hardware, and being
patient with me as I took forever to get around to writing this.

callback routine to ensure we don't get any stuck keys, and used
symbolic names for the keytable. Also cc'ing Florian this time, who I
believe is the original mod-mce author...

3f5c4c7332 [media] rc: fix ghost keypresses with certain hw
With hardware that has to use ir_raw_event_store_edge to collect IR
sample durations, we were not doing an event reset unless
IR_MAX_DURATION had passed. That's around 4 seconds. So if someone
presses up, then down, with less than 4 seconds in between, they'd get
the initial up, then up and down upon pressing down.

To fix this, I've lowered the "send a reset event" logic's threshold to
the input device's REP_DELAY (defaults to 500ms), and with an
saa7134-based GPIO-driven IR receiver in a Hauppauge HVR-1150, I get
*much* better behavior out of the remote now. Special thanks to Devin
for providing the hardware to investigate this issue.

83587839d6 [media] ir-raw: Properly initialize the IR event (BZ#27202)
Changeset 4651918a4a changed the way events
are stored. However, it forgot to fix ir_raw_event_store_edge() to work
with the new way. Due to that, the decoders will likely do bad things.
