Subject: [PATCH v2 8/9] media: fsl-viu: Constify ioreadX() iomem argument (as in generic implementation)
Date: Wed,  8 Jan 2020 21:05:27 +0100	[thread overview]
Message-ID: <20200108200528.4614-9-krzk__45515.6877332897$1578514071$gmane$org@kernel.org> (raw)
In-Reply-To: <20200108200528.4614-1-krzk@kernel.org>

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.
