From 3db1200ca21f3c63c9044185dc5762ef996848cb Mon Sep 17 00:00:00 2001 From: Frank Rowand Date: Fri, 9 Jun 2017 17:26:32 -0700 Subject: clocksource/drivers/arm_arch_timer: Fix read and iounmap of incorrect variable Fix boot warning 'Trying to vfree() nonexistent vm area' from arch_timer_mem_of_init(). Refactored code attempts to read and iounmap using address frame instead of address ioremap(frame->cntbase). Fixes: c389d701dfb70 ("clocksource: arm_arch_timer: split MMIO timer probing.")
