From 7ae281b05c0cebef4ef0643e74300fbe84760c3c Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 23 Jun 2020 09:09:02 +0200 Subject: [PATCH] scripts/kernel-doc: handle function pointer prototypes 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.
