Subject: [PATCH 4.4 036/162] i2c: imx: dont print error message on probe defer

From: Lucas Stach <l.stach@...gutronix.de>

[ Upstream commit fece4978510e43f09c8cd386fee15210e8c68493 ]

Probe deferral is a normal operating condition in the probe function,
so don't spam the log with an error in this case.
