[PATCH] kbuild: remove srctreie path from CHECK output

[PATCH] kbuild: remove srctreie path from CHECK output

[Ben Dooks]

The build does not put the full kernel path in when
building outputs, so do the same when the check is
run to make the output more consistent.

turn the following:
  CC      arch/riscv/lib/delay.o
  CHECK   /home/ben/linux/arch/riscv/lib/delay.c

into:
  CC      arch/riscv/lib/delay.o
  CHECK   arch/riscv/lib/delay.c

Hi Ben,

There is a typo in the subject.

I don't have a strong objection to this patch but I know there are
plenty of other places in the build log that will use a full source
path, so this doesn't fully address that inconsistency (and I am not
sure it is inconsistent to begin with, as most build targets are
relative to the build directory whereas files from the source tree have
to be absolute when the build is done outside the tree). But this seems
reasonable enough.

Applied to kbuild/linux.git (kbuild-next-unstable), thanks!

      https://git.kernel.org/kbuild/c/fba1a1ac

Please look out for regression or issue reports or other follow up
comments, as they may result in the patch/series getting dropped,
reverted or modified (e.g. trailers). Patches applied to the
kbuild-next-unstable branch are accepted pending wider testing in
linux-next and any post-commit review; they will generally be moved
to the kbuild-next branch in about a week if no issues are found.

Best regards,
