The quilt patch titled
     Subject: checkpatch: always parse orig_commit in fixes tag
has been removed from the -mm tree.  Its filename was
     checkpatch-always-parse-orig_commit-in-fixes-tag.patch

This patch was dropped because it was merged into the mm-nonmm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: checkpatch: always parse orig_commit in fixes tag

Do not require the presence of `$balanced_parens` to get the commit SHA;
this allows a `Fixes: deadbeef` tag to get a correct suggestion rather
than a suggestion containing a reference to HEAD.

Given this patch:

: From: Tamir Duberstein <tamird@gmail.com>
: Subject: Test patch
: Date: Fri, 25 Oct 2024 19:30:51 -0400
: 
: This is a test patch.

: Fixes: bd17e036b495

: +Test.


Before:

WARNING: Please use correct Fixes: style 'Fixes: <12 chars of sha1> ("<title line>")' - ie: 'Fixes: c10a7d25e68f ("Test patch")'

After:

WARNING: Please use correct Fixes: style 'Fixes: <12 chars of sha1> ("<title line>")' - ie: 'Fixes: bd17e036b495 ("checkpatch: warn for non-standard fixes tag style")'



The prior behavior incorrectly suggested the patch's own SHA and title
line rather than the referenced commit's.  This fixes that.

Ironically this:

Fixes: bd17e036b495 ("checkpatch: warn for non-standard fixes tag style")
