Subject: [PATCH 1/2] kernel-doc: stricter function pointer recognition

From: Randy Dunlap <randy.dunlap@...cle.com>

Be more careful about function pointer args:
look for "(...*" instead of just "(".

This line in include/linux/input.h fools the current kernel-doc script
into deciding that this is a function pointer:

	unsigned long ffbit[NBITS(FF_MAX)];
