The users of __LOG_PREFIX require that it is 0-terminated. Currently this requirement is only encoded in safety comments. Switch to CStr which can guarantee this invariant through the type system. As __LOG_PREFIX and Module::NAME are now identical, reuse the former to implement the latter. Signed-off-by: Thomas Weißschuh <linux@weissschuh.net>
