Subject: [PATCH v3 3/5] i2c: exynos5: Remove suspension check
Date: Thu, 17 Jul 2014 16:48:38 +0200	[thread overview]
Message-ID: <1405608520-5644-3-git-send-email-hechtb@gmail.com> (raw)
In-Reply-To: <1405608520-5644-1-git-send-email-hechtb@gmail.com>

We now take care of suspension in the i2c core code. So we can remove this
check here.
