Some hubs are forgetful, and end up forgetting whatever GUID we set previously after we do a suspend/resume cycle. This can lead to hotplugging breaking (along with probably other things) since the hub will start sending connection notifications with the wrong GUID. As such, we need to check on resume whether or not the GUID the hub is giving us is valid.

When userspace closes a handle, we remove it from the file->object_idr and then tell the driver to drop its references to that file/handle. However, as the file/handle is already available again for reuse, it may be reallocated back to userspace and active on a new object before the driver has had a chance to drop the old file/handle references. Whilst calling back into the driver, we have to drop the file->table_lock spinlock and so to prevent reusing the closed handle we mark that handle as stale in the idr, perform the callback and then remove the handle. We set the stale handle to point to the NULL object, then any idr_find() whilst the driver is removing the handle will return NULL, just as if the handle is already removed from idr. Note: This will be used to have a direct handle -> vma lookup table, instead of first a handle -> obj lookup, and then an (obj, vm) -> vma lookup. v2: Use NULL rather than an ERR_PTR to avoid having to adjust callers. idr_alloc() tracks existing handles using an internal bitmap, so we are free to use the NULL object as our stale identifier. v3: Needed to update the return value check after changing from using the stale error pointer to NULL.

__drm_atomic_helper_plane_destroy_state calls drm_framebuffer_unreference, which means that if drm_framebuffer_free is called before plane->destroy freed memory will be accessed. A similar case happens for the blob list, which was freed before the crtc state was, resulting in the unreference_blob from crtc_destroy_state pointing to garbage memory causing another opportunity for a GPF.

It may caused a dead lock if we flush the hpd work in bridge disable time. The normal flow would like: IN --> DRM IOCTL 1. Acquire crtc_ww_class_mutex (DRM IOCTL) IN --> analogix_dp_bridge 2. Acquire hpd work lock (Flush hpd work) 3. HPD work already in idle, no need to run the work function. OUT <-- analogix_dp_bridge OUT <-- DRM IOCTL The dead lock flow would like: IN --> DRM IOCTL 1. Acquire crtc_ww_class_mutex (DRM IOCTL) IN --> analogix_dp_bridge 2. Acquire hpd work lock (Flush hpd work) IN --> analogix_dp_hotplug IN --> drm_helper_hpd_irq_event 3. Acquire mode_config lock (This lock already have been acquired in previous step 1) ** Dead Lock Now ** It's wrong to flush the hpd work in bridge->disable time, I guess the original code just want to ensure the delay work must be finish before encoder disabled. The flush work in bridge disable time is try to ensure the HPD event won't be missed before display card disabled, actually we can take a fast respond way(interrupt thread) to update DRM HPD event to fix the delay update and possible dead lock.

Split the dp core driver from exynos directory to bridge directory, and rename the core driver to analogix_dp_*, rename the platform code to exynos_dp. Beside the new analogix_dp driver would export six hooks. "analogix_dp_bind()" and "analogix_dp_unbind()" "analogix_dp_suspned()" and "analogix_dp_resume()" "analogix_dp_detect()" and "analogix_dp_get_modes()" The bind/unbind symbols is used for analogix platform driver to connect with analogix_dp core driver. And the detect/get_modes is used for analogix platform driver to init the connector. They reason why connector need register in helper driver is rockchip drm haven't implement the atomic API, but Exynos drm have implement it, so there would need two different connector helper functions, that's why we leave the connector register in helper driver.
