The bug is here: if (nvkm_cstate_valid(clk, cstate, max_volt, clk->temp)) return cstate; The list iterator value 'cstate' will *always* be set and non-NULL by list_for_each_entry_from_reverse(), so it is incorrect to assume that the iterator value will be unchanged if the list is empty or no element is found (In fact, it will be a bogus pointer to an invalid structure object containing the HEAD). Also it missed a NULL check at callsite and may lead to invalid memory access after that. To fix this bug, just return 'encoder' when found, otherwise return NULL. And add the NULL check.

Since this driver has been changed to use the resource managed devm_drm_of_get_bridge() to get bridge from ->attach(), it's unnecessary to call drm_of_panel_bridge_remove() to remove the bridge from ->detach(). So, let's drop the drm_of_panel_bridge_remove() function call. As nwl_dsi_bridge_detach() only calls drm_of_panel_bridge_remove(), it can also be dropped.

Jani Nikula authored
There's no need to handle complicated scenarios or debug log when filtering blocks that have already been identified as invalid. Simplify by adding an edid_block_valid() helper that operates on const data and prints nothing.

Add edid_block_check() that only checks the EDID block validity, without any actions. Turns out it's simple and crystal clear. Rewrite drm_edid_block_valid() around it, keeping all the functionality fairly closely the same, warts and all. Turns out it's incredibly complicated for a function you'd expect to be simple, with all the fixing and printing and special casing. (Maybe we'll want to simplify it in the future.)

Christian König authored
So far we had the approach of using a directed acyclic graph with the dma_resv obj. This turned out to have many downsides, especially it means that every single driver and user of this interface needs to be aware of this restriction when adding fences. If the rules for the DAG are not followed then we end up with potential hard to debug memory corruption, information leaks or even elephant big security holes because we allow userspace to access freed up memory. Since we already took a step back from that by always looking at all fences we now go a step further and stop dropping the shared fences when a new exclusive one is added. v2: Drop some now superflous documentation v3: Add some more documentation for the new handling.

This reverts commit c206c7fa. In order to avoid any probe ordering issues, the I2C based downstream bridge drivers now register and attach the DSI devices at the probe instead of doing it on drm_bridge_function.attach(). Examples of those commits are: commit <6ef7ee48> ("drm/bridge: sn65dsi83: Register and attach our DSI device at probe") commit <d89078c3> ("drm/bridge: lt8912b: Register and attach our DSI device at probe") commit <864c49a3> ("drm/bridge: adv7511: Register and attach our DSI device at probe") dw-mipi-dsi has panel or bridge finding code based on previous downstream bridges, so revert the same and make the panel or bridge funding in host attach as before.
