Subject: clocksource/drivers/tango-xtal: Fix boot hang due to incorrect test
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=16eeed7e5558a3dcf30f75526a896b2632f299f9;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

clocksource/drivers/tango-xtal: Fix boot hang due to incorrect test

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")
