The\ncaller qla2x00_status_entry() acknowledges this on the very same status\npath, re-fetching GET_CMD_SP(sp) and bailing out with the \"Command\nalready returned\" message when it is NULL -- but that check runs only\nafter qla_chk_edif_rx_sa_delete_pending() has already dereferenced the\npointer, so a NULL cmd crashes the kernel in interrupt context.\n\nReturn early when cmd is NULL, before
