drm_writeback.h included a lot of nice kernel-doc comments. Wire it up so the header file is included in the kernel-doc generated documentation.

2020-04-06drm/dp_mst: Don't drop NAKs for down responsesLyude Paul
It looks like that when we introduced the ability to handle multiple down requests at once, we accidentally started dropping NAK replies - causing sideband messages which got NAK'd to seemingly timeout and cause all sorts of weirdness. So, fix this by making sure we don't return from drm_dp_mst_handle_down_rep() early, but instead treat NAKs like any other message.

2020-04-03drm/amd/amdgpu_dm/mst: Remove ->destroy_connector() callbackLyude Paul
Pankaj Bharadiya started cleaning up the MST connector callbacks a while ago, as I pointed out that they are the same across every driver and don't serve much purpose. There was one callback that was left over though from amdgpu, that we delayed removing due to not being completely sure as to whether or not it was needed. So, I've read through said callback and can confirm it's not at all needed. Pretty much all of the work that is done in dm_dp_destroy_mst_connector() can be done in dm_dp_mst_connector_destroy(). Additionally, I've removed some bits that didn't actually do anything: * Removed DRM_INFO message we were printing, this shouldn't be info level and there's more appropriate drm debugging flags that should be used instead * Removed amdgpu_dm_update_freesync_caps() - reading into this function, it doesn't actually do anything important and I'm not sure why it was ever being called here * Stop clearing aconnector->dc_sink - this also doesn't do anything * Stop clearing link settings in dc_link - this also doesn't do anything * Also, use shorter variable Signed-off-by: Lyude Paul <lyude@redhat.com> Cc: Pankaj Bharadiya <pankaj.laxminarayan.bharadiya@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200331205740.135525-3-lyude@redhat.com Reviewed-by: Alex Deucher <alexdeucher@gmail.com>
