[v5,67/80] drm/loongson: Run DRM default client setup

Commit Message

Thomas Zimmermann Sept. 24, 2024, 7:13 a.m. UTC

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 loongson driver specifies a preferred color mode of 32. As this
is the default if no format has been given, leave it out entirely.

v5:
- select DRM_CLIENT_SELECTION
