    Subject[03/53] [SCSI] hpsa: Disable ASPM
    3.0-stable review patch.  If anyone has any objections, please let me know.

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

    From: Matthew Garrett <mjg@redhat.com>

    commit e5a44df85e8d78e5c2d3d2e4f59b460905691e2f upstream.

    The Windows driver .inf disables ASPM on hpsa devices. Do the same because the
    selection of a non default ASPM policy can cause the device to hang.
