    Subject[ 131/175] PM / shmobile: Make MTU2 driver use pm_genpd_dev_always_on()
    3.3-stable review patch.  If anyone has any objections, please let me know.

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


    From: Rafael J. Wysocki <rjw@sisk.pl>

    Commit 57d13370cfaf6017c68981e66ff5b3bf20a2705c upstream.

    Make the MTU2 clocksource driver mark its device as "always on"
    using pm_genpd_dev_always_on() to protect it from surprise power
    removals.
