    Subject[022/244] xHCI: fix port U3 status check condition
    3.0-stable review patch.  If anyone has any objections, please let us know.

    ------------------

    From: Andiry Xu <andiry.xu@amd.com>

    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.
