From 019a35f1142b1cd153c8a38338515e633ec0cf77 Mon Sep 17 00:00:00 2001 From: Andiry Xu Date: Thu, 6 Jan 2011 15:43:17 +0800 Subject: [PATCH] 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.
