drm_fb_helper_init — initialize a drm_fb_helper structure
int drm_fb_helper_init ( | struct drm_device * dev, |
| struct drm_fb_helper * fb_helper, | |
| int crtc_count, | |
int max_conn_count); |

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 call drm_fb_helper_prepare before calling this function.
