NAME
       drm_fb_helper_init - initialize a drm_fb_helper structure

SYNOPSIS
       int drm_fb_helper_init(struct drm_device * dev, struct drm_fb_helper * fb_helper, int crtc_count, int max_conn_count);

ARGUMENTS
       dev
	   drm device

       fb_helper
	   driver-allocated fbdev helper structure to initialize

       crtc_count
	   maximum number of crtcs to support in this fbdev emulation

       max_conn_count
	   max connector count

DESCRIPTION
       This allocates the structures for the fbdev helper with the given limits. Note that this won't yet touch the hardware (through the driver
       interfaces) nor register the fbdev. This is only done in drm_fb_helper_initial_config to allow driver writes more control over the exact
       init sequence.

       Drivers must set fb_helper->funcs before calling drm_fb_helper_initial_config.

RETURNS
       Zero if everything went ok, nonzero otherwise.
