Init data marked const should be annotated with __initconst for correctness and not __initdata. In some cases the array gathering references to that data has to be marked const as well. This fixes LTO builds that otherwise fail with section mismatch errors. Signed-off-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Olof Johansson <olof@lixom.net>
