Subject: [PATCH v2 4/9] rtc: pcf2123: convert to devm_rtc_allocate_device
Date: Wed, 14 Aug 2019 17:09:57 +0200
Message-ID: <20190814151002.7324-4-alexandre.belloni@bootlin.com> (raw)
In-Reply-To: <20190814151002.7324-1-alexandre.belloni@bootlin.com>

This allows further improvement of the driver. Also remove the unecessary
error string as the core will already display error messages.
