Subject: [RFT 02/13] sh: Constify ioreadX() iomem argument (as in generic implementation)
Date:   Tue,  7 Jan 2020 17:53:00 +0100
Message-Id: <1578415992-24054-4-git-send-email-krzk@kernel.org>
In-Reply-To: <1578415992-24054-1-git-send-email-krzk@kernel.org>
References: <1578415992-24054-1-git-send-email-krzk@kernel.org>
Sender: linux-wireless-owner@vger.kernel.org
Precedence: bulk

The ioreadX() helpers have inconsistent interface.  On some architectures
void *__iomem address argument is a pointer to const, on some not.

Implementations of ioreadX() do not modify the memory under the address
so they can be converted to a "const" version for const-safety and
consistency among architectures.
