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.
