[PATCH 4.19 201/220] hwmon: (pwm-fan) Silence error on probe deferral

[Greg Kroah-Hartman]

From: Thierry Reding <treding@xxxxxxxxxx>

[ Upstream commit 9f67f7583e77fe5dc57aab3a6159c2642544eaad ]

Probe deferrals aren't actual errors, so silence the error message in
case the PWM cannot yet be acquired.
