[Disclaimer, I can't speak for LIRC upstream]

Since kernel 2.6.36, lirc's -previously out-of-tree- kernel modules 
have been merged into the mainline kernel[1], some as staging drivers, 
some have been properly ported to the new RC_CORE subsystem (which new 
drivers should adhere to). As such the best curse of action would be 
submit your driver to lkml and the linux-media mailing list, so that
it can be merged mainline as well, rather than introducing yet another
out-of-tree module. Doing this might involve a little more effort, like
using RC_CORE, providing device tree bindings and reacting to the 
kernel- and v4l maintainers' suggestions, but that would be the best
way forward.

[1]	the existing kernel modules provided by the lirc tarball under
	drivers/ are probably best considered to be courtesy copies for
	older kernels (<<2.6.36), they definately haven't been touched
	since the 0.9.0 release (while the in-kernel and staging drivers
	have seen significant development and bugfixes). It's probably 
	quite likely that they will be dropped from future lirc releases.
