From ea2a14da0f191e93c0924acb4ab8a9009e33de81 Mon Sep 17 00:00:00 2001 From: zain wang Date: Mon, 5 Mar 2018 09:57:39 +0100 Subject: [PATCH] drm/bridge: analogix_dp: Don't power bridge in analogix_dp_bind MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The bridge does not need to be powered in analogix_dp_bind(), so remove the calls to pm_runtime_get()/phy_power_on()/analogix_dp_init_dp() as well as their power-off counterparts.
