 arch/x86/tools: Removed headers in relocs_32.c scripts/basic: Removed
headers
 in fixdep.c drivers/pps: Removed headers in pps.c drivers/input: Removed
 headers in input-mt.c

These changes compile for x86, x86_64, and powerpc (Those were the only
ones fairly tested) under defconfig. This aims to clean up code and
simplify the files for developers. This will also contribute to start of
decluttering the environment.

Hi Oli,

thanks for your contribution.  Some comments below:

Usually, patch mails do not contain mail headers within their body; the
only possible exception is 'From:' if the sender is not the patch
author.  These additional headers prevent the usual patch application
(e.g. 'git am <mail').

A commit subject should start with a subsystem identifier.  A commit
message should tell about the what and why of the patch, followed by a
'Signed-of-by'.  E.g.:

   kbuild: fixdep: Remove unused includes

   Remove unused #include statements for clean up.

   Signed-off-by: Your Name <your.e.mail@addre.ss>

(More complex changes require more details commit message).

Please check Documentation/process/submitting-patches.rst.

The change in scripts/basic/fixdep.c looks good to me.  Do you want to
prepare a new kbuild-only patch and want me to take it for kbuild?

Kind regards,
Nicolas
