[PATCH 2/2 v2] staging: fsl-mc: do not print error in case of defer probe error

From: Nipun Gupta
Date: Mon Dec 11 2017 - 04:21:45 EST


Devices on MC bus can be deferred because of dependencies on other modules
(such as IOMMU). Those are not the actual errors; as probing is again
done by the kernel at later stages. So this patch avoids the error print
in such case.
