Howto add an existing kernel module (kmod package)

Hi,

maybe short question: How to add an extsting in tree kernel module to LEDE ?
The right way, so it could get commited upstream..
Short example or diff/commit of another similar thing should be enough..

I'm after /drivers/media/rc/ati_remote.c (and rc_core as dependency) which is there and compiles fine, but is not selectable in LEDE "make menuconfig" (?)
