Drivers' .remove and .shutdown callbacks are executed on different code paths. The former is called when a device is removed from the bus, while the latter is called at system shutdown time to quiesce the device. This means that some overlap exists between the two, because both have to take care of properly shutting down the hardware. But currently the logic used in these two callbacks isn't consistent in msm drivers, which could lead to kernel panic. For example, on .remove the component is deleted and its .unbind callback leads to the hardware being shutdown but only if the DRM device has been marked as registered. That check doesn't exist in the .shutdown logic and this can lead to the driver calling drm_atomic_helper_shutdown() for a DRM device that hasn't been properly initialized. A situation like this can happen if drivers for expected sub-devices fail to probe, since the .bind callback will never be executed. If that is the case, drm_atomic_helper_shutdown() will attempt to take mutexes that are only initialized if drm_mode_config_init() is called during a device bind. This bug was attempted to be fixed in commit 623f279c ("drm/msm: fix shutdown hook in case GPU components failed to bind"), but unfortunately it still happens in some cases as the one mentioned above, i.e: systemd-shutdown[1]: Powering off. kvm: exiting hardware virtualization platform wifi-firmware.0: Removing from iommu group 12 platform video-firmware.0: Removing from iommu group 10 ------------[ cut here ]------------ WARNING: CPU: 6 PID: 1 at drivers/gpu/drm/drm_modeset_lock.c:317 drm_modeset_lock_all_ctx+0x3c4/0x3d0 ...

As it turns out: while Nvidia does actually have interlacing knobs on their GPU still pretty much no current GPUs since Volta actually support it. Trying interlacing on these GPUs will result in NVDisplay being quite unhappy like so: nouveau 0000:1f:00.0: disp: chid 0 stat 00004802 reason 4 [INVALID_ARG] mthd 2008 data 00000001 code 00080000 nouveau 0000:1f:00.0: disp: chid 0 stat 10005080 reason 5 [INVALID_STATE] mthd 0200 data 00000001 code 00000001 So let's fix this by following the same behavior Nvidia's driver does and disable interlacing entirely.

The reference 'child' in the iteration of for_each_available_child_of_node() is only escaped out into a local variable which is only used to check its value. So we still need to the of_node_put() when breaking of the for_each_available_child_of_node() which will automatically increase and decrease the refcount.

At both suspend and disconnect, we should rather cancel the pending URBs immediately. For the suspend case, the display will be turned off, so it makes no sense to process the rendering. And for the disconnect case, the device may be no longer accessible, hence we shouldn't do any submission. Tested-by:

UDL driver uses a semaphore for controlling the emptiness of FIFO in a slightly funky way. This patch replaces it with a wait queue and controls the emptiness with the standard wait_event*() macro instead, which is a more straightforward implementation.
