Locally, I am running 6.12 with these two extra dependencies applied:

drm/fbdev-dma: Support struct drm_driver.fbdev_probeRework fbdev probing to support fbdev_probe in struct drm_driver and reimplement the old fb_probe callback on top of it. Provide an initializer macro for struct drm_driver that sets the callback according to the kernel configuration. This change allows the common fbdev client to run on top of DMA- based DRM drivers.

drm/panel-mipi-dbi: Run DRM default client setupCall drm_client_setup() to run the kernel's default client setup for DRM. Set fbdev_probe in struct drm_driver, so that the client setup can start the common fbdev client. v5: - select DRM_CLIENT_SELECTION Signed-off-by: Thomas Zimmermann tzimmermann@suse.de Cc: "Noralf Trønnes" noralf@tronnes.org Acked-by: Noralf Trønnes noralf@tronnes.org Link: https://patchwork.freedesktop.org/patch/msgid/20240924071734.98201-32-tzimme...
I have only tested panel-mipi-dbi (the only display available on the board I use). I am unsure if applying these extra patches to linux-6.12 stable is safe or if they could cause issues with other fbdev drivers.
Can you send these as a patch series for us to consider applying?
thanks,
