Subject: [PATCH 1/2] clocksource/drivers/timer-of: Do not warn on deferred probe
Date:   Wed, 21 Aug 2019 16:02:40 +0100

Deferred probe is an expected return value for clk_get() on many
platforms. The driver deals with it properly, so there's no need
to output a warning that may potentially confuse users.
