Public bug reported:
Commit 8781125 backported a change to add the drm_client_setup()
function and the DRM_CLIENT_SELECTION configuration option, but didn't
packport any of the changes to make in-kernel DRM clients actually use
that function or select the config option. Thus, enabling the option
isn't possible and drm_client_setup() is always compiled to a stub
function that does nothing.
At compile time, nvidia-drm checks for the presence of
drm_client_setup() and calls that instead of drm_fbdev_ttm_setup() if
it's loaded with the modeset=1 and fbdev=1 parameters, which results in
a blank screen if CONFIG_DRM_CLIENT_SELECTION=n.
Update the option to make it selectable and select it in the nvidia-6.11
annotations file.
