That is you must not do: *axxia_dt_match[0] = 'k'; but axxia_dt_match[0] = "different string"; is fine. So the annotation __initconst is wrong and yields a compiler error when other really const variables are added with __initconst. As the struct machine_desc member dt_compat is declared as const char *const *dt_compat; making the arrays const is the better alternative over changing all annotations to __initdata.
