Subject[PATCH] checkpatch: Improve Gerrit Change-Id: test
From
Date
The Gerrit Change-Id: entry is sometimes placed after a Signed-off-by:
line. When this occurs, the Gerrit warning is not currently emitted
as the first Signed-off-by: signature sets a flag to stop looking.

Change the test to add a test for the --- patch separator and emit the
warning before any before the --- and also before any diff file name.

Signed-off-by: Joe Perches <joe@perches.com>
Tested-by: John Stultz <john.stultz@linaro.org>
