scripts: kernel-doc: fix typedef parsing
The include/linux/genalloc.h file defined this typedef: typedef unsigned long (*genpool_algo_t)(unsigned long *map,unsigned long size,unsigned long start,unsigned int nr,void *data, struct gen_pool *pool, unsigned long start_addr); Because it has a type composite of two words (unsigned long), the parser gets the typedef name wrong: .. c:macro:: long **Typedef**: Allocation callback function type definition Fix the regex in order to accept composite types when defining a typedef for a function pointer.
