This issue can also be seen when doing a make clean and do a git status

-- 8< --
Changes not staged for commit:
  (use "git add/rm <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
deleted:    lib/acpi/dsdt.c

After applying this patch this cannot be seen anymore.
