[PATCH v4 24/80] drm/logicvc: Run DRM default client setup

[Thomas Zimmermann]

Call 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.

The logicvc driver specifies a preferred color mode from the value
in struct drm_mode_config.preferred_depth. The fbdev client also
looks at this value for the default pixel format. Thus remove the
format selection from logicvc.
