This patch takes care of two entries from Dan's list: drivers/ata/sata_sil.c +535 sil_interrupt(13) warning: variable derefenced before check 'ap' drivers/ata/sata_mv.c +2517 mv_unexpected_intr(6) warning: variable derefenced before check 'ap' and of another needless NULL pointer check in pata_octeon_cf.c.
