2023-03-22drm/bridge: lt8912b: return EPROBE_DEFER if bridge is not foundMatheus Castello
Returns EPROBE_DEFER when of_drm_find_bridge() fails, this is consistent with what all the other DRM bridge drivers are doing and this is required since the bridge might not be there when the driver is probed and this should not be a fatal failure.

2023-03-22drm/fbdev-generic: Always use shadow bufferingThomas Zimmermann
Remove all codepaths that implement fbdev output directly on GEM buffers. Always allocate a shadow buffer in system memory and set up deferred I/O for mmap. The fbdev code that operated directly on GEM buffers was used by drivers based on GEM DMA helpers. Those drivers have been migrated to use fbdev-dma, a dedicated fbdev emulation for DMA memory. All remaining users of fbdev-generic require shadow buffering. Memory management of the remaining callers uses TTM, GEM SHMEM helpers or a variant of GEM DMA helpers that is incompatible with fbdev-dma. Therefore remove the unused codepaths from fbdev-generic and simplify the code. Using a shadow buffer with deferred I/O is probably the best case for most remaining callers. Some of the TTM-based drivers might benefit from a dedicated fbdev emulation that operates directly on the driver's video memory.
