drm/i915: remove redundant repeated checks on err

[PATCH][next] drm/i915: remove redundant repeated checks on err

Posted by Colin Ian King 6 months, 1 week ago

There are a couple of redundant repeated checks on err being non-zero that
are always true because they are inside a previous check on err being
non-zero. Remove the duplicated checks.
