I believe that'd be -

static const char *const kmsg_reasons[]

rather than what was originally in the code -

static const char const *kmsg_reasons[]

Read right-to-left, the first is a constant pointer to a char constant;
the second is a pointer to a constant character constant.   I suspect
the first is what was intended.
