Subject: [PATCH 2/4] drm/dp_mst: Reformat drm_dp_check_act_status() a bit
Date:   Fri,  3 Apr 2020 16:07:54 -0400
Message-Id: <20200403200757.886443-3-lyude@redhat.com>
In-Reply-To: <20200403200757.886443-1-lyude@redhat.com>
References: <20200403200757.886443-1-lyude@redhat.com>
MIME-Version: 1.0
Content-Transfer-Encoding: quoted-printable
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Just add a bit more line wrapping, get rid of some extraneous
whitespace, remove an unneeded goto label, and move around some variable
declarations. No functional changes here.

Signed-off-by: Lyude Paul <lyude@redhat.com>
[this isn't a fix, but it's needed for the fix that comes after this]
Fixes: ad7f8a1f9ced ("drm/helper: add Displayport multi-stream helper (v0=
.6)")
