Subject: checkpatch: don't emit unified-diff error for rename-only patches
I generated a patch with `git format-patch` which checkpatch thinks is
invalid:
$ ./scripts/checkpatch.pl lpc-dt/0006-mfd-dt-Move-syscon-bindings-to-syscon-subdirectory.patch
WARNING: added, moved or deleted file(s), does MAINTAINERS need updating?
Documentation/devicetree/bindings/mfd/{ => syscon}/aspeed-scu.txt | 0
ERROR: Does not appear to be a unified-diff format patch
total: 1 errors, 1 warnings, 0 lines checked
NOTE: For some of the reported defects, checkpatch may be able to
mechanically convert to the typical style using --fix or --fix-inplace.
lpc-dt/0006-mfd-dt-Move-syscon-bindings-to-syscon-subdirectory.patch has style problems, please review.
NOTE: If any of the errors are false positives, please report
them to the maintainer, see CHECKPATCH in MAINTAINERS.
The patch in question was all renames with no edits, giving 100% similarity and
thus no diff markers.
Set '$is_patch = 1;' in the add/remove/rename detection to avoid
generating spurious warnings.
