checkpatch stops processing at an empty commit

[Tomi Valkeinen]

Hi,

I use empty commits as "banner" commits, and it seems that checkpatch stops
processing commits when it encounters such an empty commit. This happens
both when using checkpatch for patch files and when using the -g option
to check the git branch.

Here I call checkpatch for a bigger range, in which the second commit
(4928b50c0e23) is an empty commit:

$ ./scripts/checkpatch.pl -g --strict --max-line-length=80 c553517a043b..aec2d6335383
---------------------------------------------------------
Commit 1bd2c75f1254 ("media: v4l2-subdev: Sort includes")
---------------------------------------------------------
total: 0 errors, 0 warnings, 0 checks, 24 lines checked

Commit 1bd2c75f1254 ("media: v4l2-subdev: Sort includes") has no obvious style problems and is ready for submission.

Commit 4928b50c0e23 ("=========================== Fixes ============================")
