Subject: clocksource/drivers/timer-of: Fix invalid iomap check
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=22ece4e3df6335e691207de1198a609e761b8640;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

clocksource/drivers/timer-of: Fix invalid iomap check

A typo in the code checks the return value of iomap against !NULL
and, thus, fails everytime the mapping succeed.

Fix this by inverting the condition in the check.
