4.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Daniel Lezcano <daniel.lezcano@xxxxxxxxxx>
commit 16eeed7e5558a3dcf30f75526a896b2632f299f9 upstream.
Commit 0881841f7e78 introduced a regression by inverting a test check
after calling clocksource_mmio_init(). That results on the system to
hang at boot time.
Fix it by inverting the test again.
Fixes: 0881841f7e78 ("Replace code by clocksource_mmio_init")
