Subject: [PATCH v2 1/3] i2c: mediatek: Register i2c adapter driver earlier
Date: Sat, 7 Jul 2018 17:29:53 +0800	[thread overview]
Message-ID: <1530955795-17714-2-git-send-email-jun.gao@mediatek.com> (raw)
In-Reply-To: <1530955795-17714-1-git-send-email-jun.gao@mediatek.com>

From: Jun Gao <jun.gao@mediatek.com>

As i2c adapter, i2c slave devices will depend on it. In order not to
block the initializations of i2c slave devices, register i2c adapter
driver at appropriate time.
