    Subject[PATCH AUTOSEL 5.2 172/249] clocksource/drivers/tegra: Restore base address before cleanup
    Date
    From: Dmitry Osipenko <digetx@gmail.com>

    [ Upstream commit fc9babc2574691d3bbf0428f007b22261fed55c6 ]

    We're adjusting the timer's base for each per-CPU timer to point to the
    actual start of the timer since device-tree defines a compound registers
    range that includes all of the timers. In this case the original base
    need to be restore before calling iounmap to unmap the proper address.
