From 219ad6c1c35c95ff99a0c65cfba0ca9996831af5 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Tue, 21 Mar 2017 17:59:20 -0700 Subject: [PATCH] nfp: remove defensive checks around ndo_open()/ndo_close() Device open and close handlers check if the device is already in the desired state. Thanks to our reconfig infrastructure this should not be necessary, there doesn't seem to be any code in the driver which depends on it. Signed-off-by: Jakub Kicinski Signed-off-by: David S.
