[PATCH] qed: Fix potential use-after-free in qed_spq_post()

From: Roland Dreier We need to check if p_ent->comp_mode is QED_SPQ_MODE_EBLOCK before calling qed_spq_add_entry(). The test is fine is the mode is EBLOCK, but if it isn't then qed_spq_add_entry() might kfree(p_ent). Signed-off-by: Roland Dreier --- drivers/net/ethernet/qlogic/qed/qed_spq.c |
