[PATCH 21/25] clocksource/drivers/tegra: Restore base address before cleanup

From: Daniel Lezcano
Date: Wed Jun 26 2019 - 10:48:33 EST


From: Dmitry Osipenko <digetx@xxxxxxxxx>

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.
