Thanks for the patch, but this has already been fixed by: commit 0c8185944a125621a1766615585238a3563ccac3 Author: Hubert Feurstein <[email protected]> Date: Wed Jan 7 14:48:17 2015 +0100 net: fec: fix NULL pointer dereference in fec_enet_timeout_work This patch initialises the fep->netdev pointer. This pointer was not initialised at all, but is used in fec_enet_timeout_work and in some error paths. Signed-off-by: Hubert Feurstein <[email protected]> Signed-off-by: David S.
