Subject: [PATCH v2 4/8] soc: qcom: smd: Use __iowrite32_copy() instead of open-coding it
Date: Wed,  2 Sep 2015 15:46:47 -0700	[thread overview]
Message-ID: <1441234011-4259-5-git-send-email-sboyd@codeaurora.org> (raw)
In-Reply-To: <1441234011-4259-1-git-send-email-sboyd@codeaurora.org>

We already have a function to do this and it silences some sparse
warnings along the way.
