Subject: drm/stm: Run DRM default client setup
X-Git-Tag: v6.13-rc1~122^2~22^2~41
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9360547eb5815e639e640662bd6d6368a5b84c9b;p=thirdparty%2Fkernel%2Flinux.git

drm/stm: Run DRM default client setup

Call drm_client_setup_with-fourcc() 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
v4:
- remove duplicated S-o-b tag (Gerd)
v2:
- use drm_client_setup_with_fourcc()
