From: Dhinakaran Pandiyan Date: Tue, 24 Jan 2017 23:49:29 +0000 (-0800) Subject: drm/dp: Store drm_device in MST topology manager X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7b0a89a6db9a5912065e174162ec4a653c9b25d6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/dp: Store drm_device in MST topology manager struct drm_dp_mst_topology_mgr currently stores a pointer to struct dev. Changing this to instead hold a pointer to drm_device is more useful as it gives access to DRM structures. This also makes it consistent with other DRM structures like drm_crtc, drm_connector etc. Signed-off-by: Dhinakaran Pandiyan Reviewed-by: Dave Airlie Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1485301777-3465-2-git-send-email-dhinakaran.pandiyan@intel.com --- diff --git a/drivers/gpu/drm/drm_dp_mst_topology.c b/drivers/gpu/drm/drm_dp_mst_topology.c index aa644487749c..122a1b04bebc 100644 --- a/drivers/gpu/drm/drm_dp_mst_topology.c +++ b/drivers/gpu/drm/drm_dp_mst_topology.c @@ -1086,7 +1086,7 @@ static void build_mst_prop_path(const struct drm_dp_mst_branch *mstb, } static void drm_dp_add_port(struct drm_dp_mst_branch *mstb, - struct device *dev, + struct drm_device *dev, struct drm_dp_link_addr_reply_port *port_msg) { struct drm_dp_mst_port *port; @@ -1104,7 +1104,7 @@ static void drm_dp_add_port(struct drm_dp_mst_branch *mstb, port->port_num = port_msg->port_number; port->mgr = mstb->mgr; port->aux.name = "DPMST"; - port->aux.dev = dev; + port->aux.dev = dev->dev; created = true; } else { old_pdt = port->pdt; @@ -2949,7 +2949,7 @@ static void drm_dp_destroy_connector_work(struct work_struct *work) * Return 0 for success, or negative error code on failure */ int drm_dp_mst_topology_mgr_init(struct drm_dp_mst_topology_mgr *mgr, - struct device *dev, struct drm_dp_aux *aux, + struct drm_device *dev, struct drm_dp_aux *aux, int max_dpcd_transaction_bytes, int max_payloads, int conn_base_id) { diff --git a/drivers/gpu/drm/i915/intel_dp_mst.c b/drivers/gpu/drm/i915/intel_dp_mst.c index 205fe4748ec5..38e3ca2f6f18 100644 --- a/drivers/gpu/drm/i915/intel_dp_mst.c +++ b/drivers/gpu/drm/i915/intel_dp_mst.c @@ -587,7 +587,8 @@ intel_dp_mst_encoder_init(struct intel_digital_port *intel_dig_port, int conn_ba /* create encoders */ intel_dp_create_fake_mst_encoders(intel_dig_port); - ret = drm_dp_mst_topology_mgr_init(&intel_dp->mst_mgr, dev->dev, &intel_dp->aux, 16, 3, conn_base_id); + ret = drm_dp_mst_topology_mgr_init(&intel_dp->mst_mgr, dev, + &intel_dp->aux, 16, 3, conn_base_id); if (ret) { intel_dp->can_mst = false; return ret; diff --git a/drivers/gpu/drm/nouveau/nv50_display.c b/drivers/gpu/drm/nouveau/nv50_display.c index cb85cb72dc1c..452da483ca01 100644 --- a/drivers/gpu/drm/nouveau/nv50_display.c +++ b/drivers/gpu/drm/nouveau/nv50_display.c @@ -3417,7 +3417,7 @@ nv50_mstm_new(struct nouveau_encoder *outp, struct drm_dp_aux *aux, int aux_max, mstm->outp = outp; mstm->mgr.cbs = &nv50_mstm; - ret = drm_dp_mst_topology_mgr_init(&mstm->mgr, dev->dev, aux, aux_max, + ret = drm_dp_mst_topology_mgr_init(&mstm->mgr, dev, aux, aux_max, max_payloads, conn_base_id); if (ret) return ret; diff --git a/drivers/gpu/drm/radeon/radeon_dp_mst.c b/drivers/gpu/drm/radeon/radeon_dp_mst.c index 6d1237d6e1b8..7d5ada3980dc 100644 --- a/drivers/gpu/drm/radeon/radeon_dp_mst.c +++ b/drivers/gpu/drm/radeon/radeon_dp_mst.c @@ -667,7 +667,7 @@ radeon_dp_mst_init(struct radeon_connector *radeon_connector) return 0; radeon_connector->mst_mgr.cbs = &mst_cbs; - return drm_dp_mst_topology_mgr_init(&radeon_connector->mst_mgr, dev->dev, + return drm_dp_mst_topology_mgr_init(&radeon_connector->mst_mgr, dev, &radeon_connector->ddc_bus->aux, 16, 6, radeon_connector->base.base.id); } diff --git a/include/drm/drm_dp_mst_helper.h b/include/drm/drm_dp_mst_helper.h index 003207670597..27f3e99f55d1 100644 --- a/include/drm/drm_dp_mst_helper.h +++ b/include/drm/drm_dp_mst_helper.h @@ -414,7 +414,7 @@ struct drm_dp_mst_topology_mgr { /** * @dev: device pointer for adding i2c devices etc. */ - struct device *dev; + struct drm_device *dev; /** * @cbs: callbacks for connector addition and destruction. */ @@ -556,7 +556,10 @@ struct drm_dp_mst_topology_mgr { struct work_struct destroy_connector_work; }; -int drm_dp_mst_topology_mgr_init(struct drm_dp_mst_topology_mgr *mgr, struct device *dev, struct drm_dp_aux *aux, int max_dpcd_transaction_bytes, int max_payloads, int conn_base_id); +int drm_dp_mst_topology_mgr_init(struct drm_dp_mst_topology_mgr *mgr, + struct drm_device *dev, struct drm_dp_aux *aux, + int max_dpcd_transaction_bytes, + int max_payloads, int conn_base_id); void drm_dp_mst_topology_mgr_destroy(struct drm_dp_mst_topology_mgr *mgr);
