Empty commit messages are a bit too thin. E.g. in this case this was an
oversight from

commit c8725f3dc0911d4354315a65150aecd8b7d0d74a

    drm/i915: Do not call retire_requests from wait_for_rendering

which means your patch here really should have Cc'ed patch author and
revierer (i.e. Chris & Brad) of the offending patch, too.

Especially in GEM where some of the interactions are _really_ tricky you
can't just remove code that looks funky. You really have to dig into the
history and find solid evidence that this is really just an oversight and
not something deeper.

Youre sob line isn't quite up to spec, it should have a full name + mail
address (like the From: line git send-email inserted).
