From a07203108494d00efdd8f2fcbf9f2f4f63110e60 Mon Sep 17 00:00:00 2001 From: Scott Feldman Date: Fri, 12 Jun 2015 21:09:44 -0700 Subject: [PATCH] rocker: gaurd against NULL rocker_port when removing ports The ports array is filled in as ports are probed, but if probing doesn't finish, we need to stop only those ports that where probed successfully. Check the ports array for NULL to skip un-probed ports when stopping. Signed-off-by: Scott Feldman Acked-by: Jiri Pirko Signed-off-by: David S.
