Subject: [PATCH 07/14] mmc: sdhci-st: simplify optional reset handling
Date: Mon, 30 Jan 2017 12:41:09 +0100 [thread overview]
Message-ID: <20170130114116.22089-7-p.zabel@pengutronix.de> (raw)
In-Reply-To: <20170130114116.22089-1-p.zabel@pengutronix.de>
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 and to
call reset_control_(de)assert unconditionally.
