    Subject[PATCH 4.9 216/222] hwmon: (pwm-fan) Silence error on probe deferral
    Date
    From: Thierry Reding <treding@nvidia.com>

    [ Upstream commit 9f67f7583e77fe5dc57aab3a6159c2642544eaad ]

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