Subject: [PATCH v2 05/11] drm/qxl: rename qxl_bo_kmap -> qxl_bo_vmap_locked
Date:   Wed, 17 Feb 2021 13:32:07 +0100
Message-Id: <20210217123213.2199186-6-kraxel@redhat.com>
In-Reply-To: <20210217123213.2199186-1-kraxel@redhat.com>

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Append _locked to Make clear that these functions should be called with
reserved bo's only.  While being at it also rename kmap -> vmap.

No functional change.
