[Freedreno] [PATCH 04/10] drm/fbdev-generic: Initialize fb-helper structure in generic setup

[Thomas Zimmermann]

Initialize the fb-helper structure immediately after its allocation
in drm_fbdev_generic_setup(). That will make it easier to fill it with
driver-specific values, such as the preferred BPP.
