Stable team, please backport upstream commits
665788572c64 ("drm/i915/vbt: don't propagate errors from intel_bios_init()")
bb1d132935c2 ("drm/i915/vbt: split out defaults that are set when there is no VBT")
to stable kernels v4.9+. The first is a small refactor that makes the
actual fix in second easier and apply cleanly.
