From: Chris Wilson Date: Wed, 1 Jun 2016 17:08:43 +0000 (+0100) Subject: drm/i915: Silence "unexpected child device config size" for VBT on 845g X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fa05178c5dc3d1a3ad370f101cad01cf9dd3bbf9;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Silence "unexpected child device config size" for VBT on 845g My old 845g complains that the child_device_size inside its VBT, version 110, is incorrect. Let's fiddle with the version matching such that it works with this VBT (i.e. treat BIOS v110 as having the same size as v108). Fixes [drm:intel_bios_init] *ERROR* Unexpected child device config size 27 (expected 33 for VBT version 110) Whether this is correct, no one knows - but it works for this particular machine.
