drm_fb_helper_single_add_all_connectors - add all connectors to fbdev emulation helper
SYNOPSIS
int drm_fb_helper_single_add_all_connectors(struct drm_fb_helper * fb_helper);
ARGUMENTS
fb_helper
fbdev initialized with drm_fb_helper_init
DESCRIPTION
This functions adds all the available connectors for use with the given fb_helper. This is a separate step to allow drivers to freely
assign connectors to the fbdev, e.g. if some are reserved for special purposes or not adequate to be used for the fbcon.
Since this is part of the initial setup before the fbdev is published, no locking is required.
