sparc: io_64.h: Replace io function-link macros
Function like macros cannot be assigned to function pointers. This patch convert the function-like macros into object-macros, that the precompiler will replace with the name of the final function. With this patch this kind of code will work: if (priv->mode_big_endian) priv.read = ioread32be; else priv.read = ioread32; Same approach has been taken on asm-generic/io.h Reported-by: kbuild test robot <fengguang.wu@intel.com> Fixes: 99082eab63449f9d spi/xilinx: Remove iowrite/ioread wrappers Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda@gmail.com> Acked-by: David S. Miller <davem@davemloft.net> Signed-off-by: David S. Miller <davem@davemloft.net>
