Yeah, just a wee bit...

Install kernel-devel that matches your running kernel, and after doing
the bp and patching, in path/to/source/drivers/media/video/, do
'make -C /usr/src/kernels/$(uname -r) M=$PWD modules'. The resulting .ko
files should work fine with your running kernel (just copy ir-kbd-i2c.ko
into /lib/modules/$(uname -r)/extra/ and run depmod, and the updated
ir-kbd-i2c should be the one that gets loaded next time you modprobe.

Alternatively, there's this:

Overkill in this case though.
