From 7ab0f2736bfe137a82a7084bbfb5f809da95cabd Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Thu, 3 Sep 2009 10:39:43 +0000 Subject: [PATCH] netdev: Remove redundant checks for CAP_NET_ADMIN in MDIO implementations dev_ioctl() already checks capable(CAP_NET_ADMIN) before calling the driver's implementation of MDIO ioctls.
