xHCI: Remove redundant variable in xhci_resume()
Set hcd->state = HC_STATE_SUSPENDED if there is a power loss during system resume or the system is hibernated, otherwise leave it be. The variable old_state is redundant and made an unreachable code path, so remove it. Signed-off-by: Andiry Xu <andiry.xu@amd.com> Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>
