The patch titled
Subject: checkpatch: check signoff when reading stdin
has been removed from the -mm tree. Its filename was
checkpatch-check-signoff-when-reading-stdin.patch
This patch was dropped because it was merged into mainline or a subsystem tree

From: Allen Hubbe <allenbh@xxxxxxxxx>
Subject: checkpatch: check signoff when reading stdin
Signoff was not checked if the filename is '-', indicating reading the
patch from stdin. Commands such as the below would not warn about a
missing signoff, because the patch filename is '-'. This change allows
checkpatch to warn about a missing signoff, even if the input filename is
'-', but only if the patch has a commit message.
git show --pretty=email | scripts/checkpatch.pl -
A more common use of checkpatch with stdin is for piping git diff through
checkpatch. The diff output would not contain a commit message, and
therefore it would not contain a signoff line. For this common use case,
a warning should not be printed about the missing signoff. With this
change we will only warn about a missing signoff if the input contains a
commit message.
git diff | scripts/checkpatch.pl -
Before this patch, a workaround for the first command was to refer to
stdin by a name other than '-'. The workaround is not an elegant
solution, because elsewhere checkpatch uses the fact that filename equals
'-', such as in setting '$vname' to 'Your patch' for stdin. The command
below would report "/dev/stdin has style problems" instead of "Your patch
has style problems."
git show --pretty=email | scripts/checkpatch.pl /dev/stdin
