2017-01-25drm/dp: Store drm_device in MST topology managerDhinakaran Pandiyan
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 <dhinakaran.pandiyan@intel.com> Reviewed-by: Dave Airlie <airlied@redhat.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1485301777-3465-2-git-send-email-dhinakaran.pandiyan@intel.com

2017-01-19drm: qxl: Open code probing sequence for qxlGabriel Krisman Bertazi
This avoids using the deprecated drm_get_pci_dev() and load() hook interfaces in the qxl driver. The only tricky part is to ensure TTM debugfs initialization happens after the debugfs root node is created, which is done by moving that code into the debufs_init() hook. Tested on qemu with igt and running a WM on top of X. Changes since v1: - Drop verification for primary minor in qxl_debugsfs_init. Changes since V2: - Put new header together with other debugfs headers.

2017-01-19drm/i915: Remove crtc->config usage from intel_modeset_readout_hw_state()Ville Syrjälä
crtc->config is on its way out. Let's reduce our dependence on it a little bit by removing it from intel_modeset_readout_hw_state(). Also replace crtc->acttive checks with crtc_state->base.active checks.
