This series aims to fix this. This series includes the patch from https://lore.kernel.org/dri-devel/YVLYh%2FSgBritG%2FRJ@qwark.sigxcpu.org/ with a `dev_warn` added. The patches are against 5.15-rc3. I've marked a single patch with a 'fixes' which is enough to unbreak the display stack in 5.15. All patches of this series can be applied independently. Changes from v1: - Review comment by Marek Vasut https://lore.kernel.org/dri-devel/67e6056a-6157-795d-908d-d65cc803c03d@denx.de/ Improve warning message - Move mxsfb patches to the end of the queue and the actual nwl fix to the front.
