  I find it helpful to be able to build the linux-media modules
for a kernel other than the one I am currently running.

This is a resend of the patch that appeared at
  https://patchwork.linuxtv.org/patch/59979/
and completely supercedes that patch.
There are no differences in the patch, just the formatting of the
submission email.
