This recipe extracts a small set of UAPI header files form the linux-imx tree.
However, the revision these headers are extracted from is already present in
our linux fork, so bitbake is currently fetching the linux-imx repo to obtain
some files that it can also obtain from our fork. This is impractical because
the repo in question is quite large (~2.80 GiB) and only getting larger with
time.
By modifying the recipe to use our linux fork instead of NXP's, we avoid having
to fetch NXP's repo.
