Subject: [PATCH] gpu/drm/hisilicon: Convert drm_atomic_helper_suspend/resume()
Message-ID: <20180719160426.GA21958@jordon-HP-15-Notebook-PC>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
User-Agent: Mutt/1.5.21 (2010-09-15)
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

convert drm_atomic_helper_suspend/resume() to use
drm_mode_config_helper_suspend/resume().

Fixed one sparse warning by making hibmc_drm_interrupt
static.
