Subject: [PATCH v2 03/14] [media] coda: simplify optional reset handling
Date: Wed, 15 Mar 2017 12:31:35 +0100	[thread overview]
Message-ID: <20170315113135.14519-1-p.zabel@pengutronix.de> (raw)

As of commit bb475230b8e5 ("reset: make optional functions really
optional"), the reset framework API calls use NULL pointers to
describe optional, non-present reset controls.

This allows to return errors from devm_reset_control_get_optional
without special cases and to call reset_control_reset unconditionally.
