Subject: [PATCH 1/3] regulator: don't emit errors in {devm_}regulator_bulk_get when defering
Date: Tue, 10 Mar 2015 00:22:06 +0100 [thread overview]
Message-ID: <9261130.uPvufuEFrr@phil> (raw)
In-Reply-To: <1429128.MSqYm0qZ9p@phil>
When {devm_}regulator_get returns -EPROBE_DEFER the driver in question will
try probing again at a later time. So don't spam the log with failure messages
as this is an expected result of probe ordering.
