commit: 5ac04bf190e6f8b17238aef179ebd7f2bdfec919 From: Andiry Xu <[email protected]> Date: Wed, 3 Aug 2011 16:46:48 +0800 Subject: [PATCH] xHCI: fix port U3 status check condition
Fix the port U3 status check when Clear PORT_SUSPEND Feature. The port status should be masked with PORT_PLS_MASK to check if it's in U3 state. This should be backported to kernels as old as 2.6.37.
