From: Dmitry Osipenko <digetx@xxxxxxxxx> [ 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.
