From 0cd71b9a43ad80f4d9a8bfde6ec6db8daf447029 Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Mon, 2 Mar 2020 14:14:28 +0000 Subject: [PATCH] regulator: pwm: Don't warn on probe deferral Deferred probe is an expected return value for devm_pwm_get(). Given that the driver deals with it properly, rather than warn on probe deferral, only output a message on probe deferral if debug level prints are enabled.
