Subject: [RESEND PATCH v2 2/9] rtl818x: Constify ioreadX() iomem argument (as in generic implementation)
Date:   Wed, 19 Feb 2020 18:50:00 +0100
Message-Id: <20200219175007.13627-3-krzk@kernel.org>
In-Reply-To: <20200219175007.13627-1-krzk@kernel.org>
References: <20200219175007.13627-1-krzk@kernel.org>
Sender: linux-kernel-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.
