2021-08-11vfio/gvt: Fix open/close when multiple device FDs are openJason Gunthorpe
The user can open multiple device FDs if it likes, however the open function calls vfio_register_notifier() on device global state. Calling vfio_register_notifier() twice will trigger a WARN_ON from notifier_chain_register() and the first close will wrongly delete the notifier and more. Since these really want the new open/close_device() semantics just change the function over.

2021-08-10drm/msm/dp: do not end dp link training until video is readyKuogee Hsieh
Initialize both pre-emphasis and voltage swing level to 0 before start link training and do not end link training until video is ready to reduce the period between end of link training and video start to meet Link Layer CTS requirement. Some dongle main link symbol may become unlocked again if host did not end link training soon enough after completion of link training 2. Host have to re train main link if loss of symbol locked detected before end link training so that the coming video stream can be transmitted to sink properly. This fixes Link Layer CTS cases 4.3.2.1, 4.3.2.2, 4.3.2.3 and 4.3.2.4.

2021-08-10drm/msm/dp: reset aux controller after dp_aux_cmd_fifo_tx() failed.Kuogee Hsieh
Aux hardware calibration sequence requires resetting the aux controller in order for the new setting to take effect. However resetting the AUX controller will also clear HPD interrupt status which may accidentally cause pending unplug interrupt to get lost. Therefore reset aux controller only when link is in connection state when dp_aux_cmd_fifo_tx() fail. This fixes Link Layer CTS cases 4.2.1.1 and 4.2.1.2.

2021-08-10drm/msm/dsi: Fix some reference counted resource leaksChristophe JAILLET
'of_find_device_by_node()' takes a reference that must be released when not needed anymore. This is expected to be done in 'dsi_destroy()'. However, there are 2 issues in 'dsi_get_phy()'. First, if 'of_find_device_by_node()' succeeds but 'platform_get_drvdata()' returns NULL, 'msm_dsi->phy_dev' will still be NULL, and the reference won't be released in 'dsi_destroy()'. Secondly, as 'of_find_device_by_node()' already takes a reference, there is no need for an additional 'get_device()'. Move the assignment to 'msm_dsi->phy_dev' a few lines above and remove the unneeded 'get_device()' to solve both issues.
