[Intel-gfx] [PATCH v2 0/4] drm/i915: Convert fbdev to DRM client

[Thomas Zimmermann]

Convert i915's fbdev code to struct drm_client. Replaces the current
ad-hoc integration. The conversion includes a number of cleanups.

As with most other driver's fbdev emulation, fbdev in i915 is now
just another DRM client that runs after the DRM device has been
registered. This allows to remove the asynchronous initialization.

I've long wanted to send out an update for this patchset. i915
is the last driver with an fbdev emulation that is not build upon
struct drm_client. Once reviewed, the patches would ideally go
into drm-misc-next, so that the old fbdev helper code can be removed.
We can also attempt to add additional in-kernel clients. A DRM-based
dmesg log or a bootsplash are commonly mentioned. DRM can then switch
easily among the existing clients if/when required.

v2:
	* fix error handling (Jani)
	* fix non-fbdev builds
	* various minor fixes and cleanups

  drm/i915: Initialize fbdev DRM client with callback functions
  drm/i915: Implement fbdev client callbacks
  drm/i915: Implement fbdev emulation as in-kernel client
