drm/omap: Pass along the format info from .fb_create() to drm_helper_mode_fill_fb_struct()
Plumb the format info from .fb_create() all the way to
drm_helper_mode_fill_fb_struct() to avoid the redundant
lookup.
For the fbdev case a manual drm_get_format_info() lookup
is needed.
The patch is based on the driver parts of the patchset at Link:
below, which missed converting the omap driver.
Due to the absence of this change in the patchset at Link:, after the
Fixed: commit below, omap_framebuffer_init() ->
drm_helper_mode_fill_fb_struct() set drm_framebuffer::format incorrectly
to NULL, which lead to the !fb->format WARN() in drm_framebuffer_init()
and causing framebuffer creation to fail. This patch fixes both of these
issues.
v2: Amend the commit log mentioning the functional issues the patch
fixes. (Tomi)
