Subject: drm/i915: Set up fb format modifier for initial plane config
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=18c5247e1e96d657334dabd8ab611001f16a62b0;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/i915: Set up fb format modifier for initial plane config

No functional changes yet since intel_framebuffer_init would have
fixed this up for us. But this is prep work to be able to handle new
tiling layouts in the initial plane config code.

Follow-up patches will start to make use of this and switch over to fb
modifiers where needed.
