The former is called when a device is removed from the bus, while\nthe latter is called at system shutdown time to quiesce the device.\n\nThis means that some overlap exists between the two, because both have to\ntake care of properly shutting down the hardware. But currently the logic\nused in these two callbacks isn't consistent in msm drivers, which could\nlead to kernel panic.\n\nFor example, on .remove the component is deleted and its .unbind callback\nleads to the hardware being shutdown but only if the DRM device has been\nmarked as registered.\n\nThat check doesn't exist in the .shutdown logic and this can lead to the\ndriver calling drm_atomic_helper_shutdown() for a DRM device that hasn't\nbeen properly initialized.\n\nA situation like this can happen if drivers for expected sub-devices fail\nto probe, since the .bind callback will never be executed. If that is the\ncase, drm_atomic_helper_shutdown() will attempt to take mutexes that are\nonly initialized if drm_mode_config_init() is called during a device bind.\n\nThis bug was attempted to be fixed in commit 623f279c7781 (\"drm/msm: fix\nshutdown hook in case GPU components failed to bind\"), but unfortunately\nit still happens in some cases as the one mentioned above, i.e:\n\n
