Subject: [PATCH AUTOSEL 5.9 01/23] drm/tegra: sor: Don't warn on probe deferral

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

[ Upstream commit cb7ff314e1d9f3d6c62fa2c392e41174721ed0b3 ]

Deferred probe is an expected return value for tegra_output_probe().
Given that the driver deals with it properly, there's no need to output
a warning that may potentially confuse users.
