Subject[PATCH 5.3 045/344] ASoC: tlv320aic31xx: suppress error message for EPROBE_DEFER
Date
From: Lucas Stach <l.stach@pengutronix.de>

[ Upstream commit b7e814deae33eb30f8f8c6528e8e69b107978d88 ]

Both the supplies and reset GPIO might need a probe deferral for the
resource to be available. Don't print a error message in that case, as
it is a normal operating condition.
