Hi John,
> Dan Carpenter pointed out that 'err' was not being set in the case
> where the GuC firmware version range check fails. Fix that.

is _a_ bug fix.
> below). It is an exceedingly low risk bug. The range check is
> asserting that the GuC firmware version is within spec. So it should
> not be possible to ever have a firmware file that fails this check. If
> larger version numbers are required in the future, that would be a
> backwards breaking spec change and thus require a major version bump,
> in which case an old i915 driver would not load that new version anyway.
