Subject: drm/i915/bios: remove a redundant NULL pointer check
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=4d70f38a760ad2879d2ebd84001c92980180f630;p=deliverable%2Flinux.git

drm/i915/bios: remove a redundant NULL pointer check

We never pass a non-NULL vbt to validate_vbt, and we can safely expect
the callers to not change.
