Subject: clocksource/drivers/tegra: Restore base address before cleanup
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fc9babc2574691d3bbf0428f007b22261fed55c6;p=linux.git

clocksource/drivers/tegra: Restore base address before cleanup

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.
