Minor issue that can only cause trouble if the last port gets an
overcurrent indication (an uncommon hardware fault) ... the variable
is only tested once after it's potentially clobbered, while the
potential clobber is on a code path that only triggers with the
experimental USB_SUSPEND config option.  AFAIK nobody yet relies
on that option; too many USB drivers still have broken suspend()
or resume() methods to rely on it.

So, worth fixing but not sweating over.

Not so.
