Subject: [PATCH 03/12] rtc: pcf85063: remove bogus i2c functionality check
Date: Mon,  1 Apr 2019 18:08:07 +0200	[thread overview]
Message-ID: <20190401160816.17859-3-alexandre.belloni@bootlin.com> (raw)
In-Reply-To: <20190401160816.17859-1-alexandre.belloni@bootlin.com>

Only smbus reads and write are done in the driver, plain i2c functionality
is not required.
