Subject: [PATCH v1 11/16] rtc: mediatek: move the declaration into a globally visible header file
Date: Fri, 23 Mar 2018 17:15:08 +0800	[thread overview]
Message-ID: <53afbe8172fb1afd809ce9ba1afeda924b9ea705.1521794177.git.sean.wang@mediatek.com> (raw)
In-Reply-To: <cover.1521794176.git.sean.wang@mediatek.com>

From: Sean Wang <sean.wang@mediatek.com>

This is in preparation for allowing other drivers can share the
declaration, so move the declaration into a globally visible header file.
