That is change:
extern struct builtin_fw __start_builtin_fw[];
extern struct builtin_fw __end_builtin_fw[];

static bool fw_get_builtin_firmware(struct firmware *fw, const char *name,
        void *buf, size_t size)
{
 struct builtin_fw *b_fw;

 for (b_fw = __start_builtin_fw; b_fw != __end_builtin_fw; b_fw++) {
--------------- CUT ------------------

to (there might already be a macro in linux which does the asm like below
already):

extern struct builtin_fw __start_builtin_fw[];
extern struct builtin_fw __end_builtin_fw[];

static bool fw_get_builtin_firmware(struct firmware *fw, const char *name,
        void *buf, size_t size)
{
 struct builtin_fw *b_fw;
 struct builtin_fw *b_fw_start = __start_builtin_fw, b_fw_end =
__end_builtin_fw;
 asm("":"+r"(b_fw_start));
 asm("":"+r"(b_fw_end));


 for (b_fw = b_fw_start; b_fw != b_fw_end; b_fw++) {
