    Subject[PATCH 3.10 07/65] usb: gadget: composite: enable BESL support
    Date
    3.10-stable review patch.  If anyone has any objections, please let me know.

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

    From: Felipe Balbi <balbi@ti.com>

    commit a6615937bcd9234e6d6bb817c3701fce44d0a84d upstream.

    According to USB 2.0 ECN Errata for Link Power
    Management (USB2-LPM-Errata-final.pdf), BESL
    must be enabled if LPM is enabled.

    This helps with USB30CV TD 9.21 LPM L1
    Suspend Resume Test.
