[PATCH v2 06/15] scripts/kernel-doc: handle function pointer prototypes

From: Mauro Carvalho Chehab
Date: Tue Jun 23 2020 - 03:09:34 EST


There are some function pointer prototypes inside the net
includes, like this one:

int (*pcs_config)(struct phylink_config *config, unsigned int mode,
phy_interface_t interface, const unsigned long *advertising);

There's nothing wrong using it with kernel-doc, but we need to
add a rule for it to parse such kind of prototype.
