[PATCH 27/29] scripts: kernel-doc: fix typedef parsing |
Date: |

From: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
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.
