From 5ca6ad7dce2f3d05bd67a15031c750c0214b7b33 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Fri, 14 Aug 2020 17:32:11 -0700 Subject: rtl818x: constify ioreadX() iomem argument (as in generic implementation) 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.
