Subject: [PATCH 4/4] i2c: designware: remove runtime suspend prevention during registration
Date: Thu, 14 Apr 2016 20:53:34 +0800	[thread overview]
Message-ID: <1460638414-5987-5-git-send-email-jszhang@marvell.com> (raw)
In-Reply-To: <1460638414-5987-1-git-send-email-jszhang@marvell.com>

Now all users make sure there won't be runtime suspend when calling
i2c_dw_probe(), so we can remove the prevention code now.
