Subject: clocksource/drivers/arm_arch_timer: Fix read and iounmap of incorrect variable
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3db1200ca21f3c63c9044185dc5762ef996848cb;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

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.")
