We didn't take the kernel_fb_helper_lock mutex, which protects that code. While at it, simplify the code - inline the function (originally shared with kgdb I think) - drop the error tracking and all the complications - drop the pointless early out, it served nothing Acked-by:

This patch restores DRM connector registration in the TC358764 bridge driver and restores usage of the old drm_panel_* API, thus allows dynamic panel registration. This fixes panel operation on Exynos5250-based Arndale board. This is equivalent to the revert of the following commits: 1644127f "drm/bridge: tc358764: add drm_panel_bridge support" 385ca38d "drm/bridge: tc358764: drop drm_connector_(un)register" and removal of the calls to drm_panel_attach()/drm_panel_detach(), which were no-ops and has been removed in meanwhile.

This reverts commit 37054fc8 ("gpu/drm: ingenic: Add option to mmap GEM buffers cached") At the very moment this commit was created, the DMA API it relied on was modified in the DMA tree, which caused the driver to break in linux-next. Revert it for now, and it will be resubmitted later to work with the new DMA API. Signed-off-by:

The new type struct dma_buf_map represents a mapping of dma-buf memory into kernel space. It contains a flag, is_iomem, that signals users to access the mapped memory with I/O operations instead of regular loads and stores. It was assumed that DMA buffer memory can be accessed with regular load and store operations. Some architectures, such as sparc64, require the use of I/O operations to access dma-map buffers that are located in I/O memory. Providing struct dma_buf_map allows drivers to implement this. This was specifically a problem when refreshing the graphics framebuffer on such systems. [1] As the first step, struct dma_buf stores an instance of struct dma_buf_map internally. Afterwards, dma-buf's vmap and vunmap interfaces are be converted. Finally, affected drivers can be fixed. v3: * moved documentation into separate patch * test for NULL pointers with !<ptr> [1] https://lore.kernel.org/dri-devel/20200725191012.GA434957@ravnborg.org/Signed-off-by:
