I think this is fine, because although it gets rid of the NULL checks
for the drm_fb_helper structure, the driver will fail to initialise
unless priv->fbdev and the fb helper successfully initialises.
It would be nice to mention that in the commit message as to why
removing those NULL checks is safe.
In any case,

Thanks.
