Subject: [PATCH v3 3/4] soc: qcom: smd: Use __ioread32_copy() instead of open-coding it
Date: Fri, 23 Oct 2015 13:01:51 -0700	[thread overview]
Message-ID: <1445630512-10888-4-git-send-email-sboyd@codeaurora.org> (raw)
In-Reply-To: <1445630512-10888-1-git-send-email-sboyd@codeaurora.org>

Now that we have a generic library function for this, replace the
open-coded instance.
