From 28898fd1a85fa37a59c090271e8be37afe710276 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Fri, 20 May 2016 17:04:22 -0700 Subject: [PATCH] checkpatch: improve --git shortcut The --git shortcut can be confused by a tag with a dash like v4.4-rc1. Improve the test to verify the expression ends with a dash followed by a numeric value. Improve the git log result to verify the " " output as well.
