Subject: [PATCH] mci: core: make mci_register -EPROBE_DEFER sensitive
Date: Wed, 11 Sep 2019 17:03:03 +0200	[thread overview]
Message-ID: <20190911150303.6567-1-m.felsch@pengutronix.de> (raw)

If the current regulator can't be requested because of -EPROBE_DEFER we
shouldn't print a error and ignore it.
