From 92c14d9b5ee86fd6cf136c01b6a87353522aebdd Mon Sep 17 00:00:00 2001 From: Jiri Benc Date: Tue, 22 Sep 2015 18:56:43 +0200 Subject: [PATCH] genetlink: simplify genl_notify The genl_notify function has too many arguments for no real reason - all callers use genl_info to get them anyway. Just pass the genl_info down to genl_notify. Signed-off-by: Jiri Benc Signed-off-by: David S.
