Just one minor nitpick.
You could 'use' the original RC5 decoder, but add a knob to it to make
it accept 15 bits instead of 14.
However, this will require some interface changes.

Well, I think that still falls down if someone, for some reason, wants
to use both an old RC5 remote and the Streamzap remote at the same
time. I think a parallel decoder is probably the best situation for
the moment, as both 14-bit RC5 and Streamzap RC5 can be decoded
simultaneously.

One option could be to change rc5 decoder to work with 3 different modes,
controlled by a sysfs node:
1) just 14 bits code;
2) just 15 bits code;
3) both 14 and 15 bits code.

For (3), it will need a timeout logic for a short period (like 2T), for the
15th bit. If nothing happens, it will assume it is 14 bits, producing a code
and resetting the finite-state machine.

By default, it would be working on 14-bits mode for normal RC decoders, and
on 15-bits mode for Streamzap.

Yet, IMHO, the better is to commit what you have currently. Just my 2 cents.
