Subject: [PATCH] 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.
Ironically this:
Fixes: bd17e036b495 ("checkpatch: warn for non-standard fixes tag style")
