Date: Fri, 20 Jun 2014 13:12:13 +0100 From: Russell King <rmk+kernel@....linux.org.uk> To: linux-arm-kernel@...ts.infradead.org Cc: Fugang Duan <B38611@...escale.com>, netdev@...r.kernel.org Subject: [PATCH RFC 06/30] net: fec: remove checking for NULL phy_dev in fec_enet_close() fep->phy_dev can not be NULL here for two reasons: - fec_enet_open() will have successfully connected the phy, or will have failed. - fec_enet_open() will have called phy_start(fep->phy_dev), which unconditionally dereferences this pointer. If it were to be NULL here, then fec_enet_open() will have already oopsed.
