Patch attached. It's applicable to current repository content.
I'm interested in knowing which budget cards have remote controls which are
compatible and provide either working output *or* dmesg output when keys are
pressed. If you have a card which is (or can be) driven by the budget-ci
module and for which a remote control interface is reported, you can add the
low half-word of the card's PCI subsystem ID as shown in the following
example (untested, since I only have a Nova-T):

If, with that patch (modified, if needed, for your card), you have a
fully-working remote control *or* you're seeing messages like
budget-ci: received key 04 address 1E
in dmesg output (and, possibly, /var/log/debug) then I'd like to know. In the
case of dmesg output, the range of key values and the range of address values
are both important and should be reported.

budget-ci: make it use ir-common and make ir-common aware of repeat events
From: Darren Salt <linux@xxxxxxxxxxxxxxxxxxxxxxxxxxx>
budget-ci changes:
Allocate enough space for the device name.
Supply a device name (for id by means other than the device node name).
Retype key_map[], and rename it ready for later removal from budget-ci.c.
Use the correct keymap for Nova-T remote controls.
Make the repeat period equal to that of the remote control, i.e. generate a
key event for every received signal - but not the *first* repeated signal
because that could be coming from a Zenith remote control. Also, the initial
repeat delay being longer is generally useful.
The driver now expects two bytes for each button press or repeat.
It must quickly process the first byte, else it risks missing the second.
The second byte contains a partial address; require (byte & 0x1F) == 0x1F,
at least for known Hauppauge devices.
Output debug information concerning unrecognised addresses.
ir-common changes:
Assume that ir->keypressed is always valid, specifically 0, 1 or 2.
Make ir_input_keydown aware of repeat events.
Kconfig:
Cause ir-common to be built if budget-ci is built.
