Subject: [PATCH 5.3 03/25] clocksource/drivers: Do not warn on probe defer

From: Jon Hunter <jonathanh@...dia.com>

commit 14e019df1e64c8b19ce8e0b3da25b6f40c8716be upstream.

Deferred probe is an expected return value on many platforms and so
there's no need to output a warning that may potentially confuse users.
