Subject: [PATCH] phy: tegra: xusb: Don't warn on probe defer
Date: Mon, 24 Feb 2020 14:36:41 +0000 [thread overview]
Message-ID: <20200224143641.5851-1-jonathanh@nvidia.com> (raw)
Deferred probe is an expected return value for tegra_fuse_readl().
Given that the driver deals with it properly, there's no need to
output a warning that may potentially confuse users.
