No objection from me, I've replied with reviewed-by for those USB patches now. thanks, greg k-h

Great, thank you. drm-devs, can I get an ack / reviewed-by for the rest of the series so that I can push this to drm-misc-next ? Regards, Hans
Here is v3 of my patchset making DP over Type-C work on devices where the Type-C controller does not drive the HPD pin on the GPU, but instead we need to forward HPD events from the Type-C controller to the DRM driver. Changes in v4: - Rebase on top of latest drm-tip - Add forward declaration for struct fwnode_handle to drm_crtc_internal.h (fixes warning reported by kernel test robot <lkp@intel.com>) - Add Heikki's Reviewed-by to patch 7 & 8 - Add Heikki's Tested-by to the series Changes in v3: - Base on top of latest drm-tip, which should fix the CI being unable to apply (and thus to test) the patches - Make intel_acpi_assign_connector_fwnodes() take a ref on the fwnode it stores in connector->fwnode and have drm_connector_cleanup() put this reference - Drop data argument from drm_connector_oob_hotplug_event() - Make the Type-C DP altmode code only call drm_connector_oob_hotplug_event() when the HPD bit in the status vdo changes - Drop the platform/x86/intel_cht_int33fe: Correct "displayport" fwnode reference patch, this will be merged independently through the pdx86 tree Changes in v2: - Replace the bogus "drm/connector: Make the drm_sysfs connector->kdev device hold a reference to the connector" patch with: "drm/connector: Give connector sysfs devices there own device_type" the new patch is a dep for patch 2/9 see the patches - Stop using a class-dev-iter, instead at a global connector list to drm_connector.c and use that to find the connector by the fwnode, similar to how we already do this in drm_panel.c and drm_bridge.c - Make drm_connector_oob_hotplug_event() take a fwnode pointer as argument, rather then a drm_connector pointer and let it do the lookup itself. This allows making drm_connector_find_by_fwnode() a drm-internal function and avoids code outside the drm subsystem potentially holding on the a drm_connector reference for a longer period. This series not only touches drm subsys files but it also touches drivers/usb/typec/altmodes/typec_displayport.c, that file usually does not see a whole lot of changes. So I believe it would be best to just merge the entire series through drm-misc, Assuming we can get an ack from Greg for merging the typec_displayport.c changes this way.
