[PATCH][-next] ixgbe: don't clear_bit on xdp_ring->state if xdp_ring is null

2018-10-04 Thread Colin King
From: Colin Ian King There is an earlier check to see if xdp_ring is null when configuring the tx ring, so assuming that it can still be null, the clearing of the xdp_ring->state currently could end up with a null pointer dereference. Fix this by only clearing the bit if xdp_ring is not null. D
