-Subject: [PATCH] igb: Fix Null-pointer dereference in igb_reset_q_vector
-
-When igb_set_interrupt_capability() calls
-igb_reset_interrupt_capability() (e.g., because CONFIG_PCI_MSI is unset),
-num_q_vectors has been set but no vector has yet been allocated.
-
-igb_reset_interrupt_capability() will then call igb_reset_q_vector,
-which assumes that the vector is allocated. As this is not the case, we
-are accessing a NULL-pointer.
-
-This patch fixes it by checking that q_vector is indeed different from
-NULL.
-
-Fixes: 02ef6e1d0b0023 (igb: Fix queue allocation method to accommodate changing during runtime)
