Rework fbdev probing to support fbdev_probe in struct drm_driver

that sets the callback in struct drm_driver according to the kernel

kernel's default client setup for DRM.
This commit also prepares support for the kernel's drm_log client
(or any future client) in i915. Using drm_log will also require vmap
support in GEM objects.
I've tested this series on an Alderlake laptop, and it effectively
breaks the boot with drm_log on i915. (I can still see the drm_log on
simpledrm, but when it switches to i915, I get a blackscreen, and the
laptop hard freezes).
Can we wait to have the proper vmap support in GEM objects, before
merging this series?
Or at least prevent drm_log to load on i915, until it is fixed?
Did you add vmap support as advised here? i915 will not support drm_log
without and this series does not add it.
A patch for vmap functions is at [1], I think.
Thanks a lot, it works much better with this patch :)
That was the missing piece to have drm_log display something on i915.
