From: Ville Syrjälä <[email protected]> Wrap intel_plane_fb_max_stride() in intel_dumb_fb_max_stride() for the purposes of dumb fb creation. I want to change intel_plane_fb_max_stride() to take a 'struct drm_format_info' instead of the 'u32 pixel_format' so we need an excplicit format info lookup in the dumb fb path and I don't really want to have that in i915_gem_dumb_create() directly.
This makes intel_plane_fb_max_stride() internal to the display code again, and thus we can pass in struct intel_display instead of struct drm_device.
