[PATCH 0/4] checkpatch: improve exit criterias

[Bjorn Andersson <bjorn.andersson@oss.qualcomm.com>]

When invoking checkpatch with the --mailback argument over a range of
patches the tool unexpectedly exits successfully on the first clean
patch. For example:

  ./scripts/checkpatch.pl --mailback --git v7.3-rc1..

Checks the single commit and then exits successfully. In contrast,
omitting --mailback causes checkpatch to check the thousands of commits
in the range.

The same behavior can be observed with --no-patch or when empty patches
are involved, which exits successfully after the first non-patch has
passed the checks, either skipping further checks or failing to return a
non-zero exit value even though errors has been reported.

Lastly, checkpatch fails with a non-zero status when invoked on a
missing patch file, but zero when invoked on a missing file.

Bjorn Andersson (4):
      checkpatch: don't stop at the first clean patch with --mailback
      checkpatch: don't stop at the first non-patch input with --no-patch
      checkpatch: don't stop at the first empty input
      checkpatch: fail on missing or unreadable files with --file
