sparc: io_64.h: Replace io function-link macros (9555b47f) · Commits · 戴 / test

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:
