[RFT 11/13] net: wireless: rtl818x: Constify ioreadX() iomem argument (as in generic implementation)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
