Subject: xHCI: fix port U3 status check condition
From: Andiry Xu <[email protected]>
commit 5ac04bf190e6f8b17238aef179ebd7f2bdfec919 upstream.
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.
