From: Joe Perches <joe@xxxxxxxxxxx> Subject: checkpatch: improve --git <commit-count> shortcut The --git <commit-count> shortcut can be confused by a tag with a dash like v4.4-rc1. Improve the test to verify the <commit-count> expression ends with a dash followed by a numeric value. Improve the git log result to verify the "<sha1> <subject>" output as well.
