    virtio: pci: constify ioreadX() iomem argument (as in generic implementation) · fe0580ac
    Krzysztof Kozlowski authored
    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.
