while you're here, can you fix the arg alignment of this
request_firmware_nowait - it looks awful right now:

int
request_firmware_nowait(
        struct module *module, bool uevent,
        const char *name, struct device *device, gfp_t gfp, void *context,
        void (*cont)(const struct firmware *fw, void *context))
{

and it could like, say, this:

int request_firmware_nowait(struct module *module, bool uevent, const char *name,
			    struct device *device, gfp_t gfp, void *context,
			    void (*cont)(const struct firmware *fw, void *context))
{

or something even more readable.
