Hi Quentin, most error branches also do set the freed pointer to NULL, please do the same. tomash > Signed-off-by: Quentin Lambert <lambert.quentin@gmail.com> > > --- > drivers/scsi/aic94xx/aic94xx_hwi.c | 4 +++- > 1 file changed, 3 insertions(+), 1 deletion(-) > > --- a/drivers/scsi/aic94xx/aic94xx_hwi.c > +++ b/drivers/scsi/aic94xx/aic94xx_hwi.c > @@ -228,8 +228,10 @@ static int asd_init_scbs(struct asd_ha_s > bitmap_bytes = (asd_ha->seq.tc_index_bitmap_bits+7)/8; > bitmap_bytes = BITS_TO_LONGS(bitmap_bytes*8)*sizeof(unsigned long); > asd_ha->seq.tc_index_bitmap = kzalloc(bitmap_bytes, GFP_KERNEL); > - if (!asd_ha->seq.tc_index_bitmap) > + if (!asd_ha->seq.tc_index_bitmap) { > + kfree(asd_ha->seq.tc_index_array); > return -ENOMEM; > + } > > spin_lock_init(&seq->tc_index_lock); > > -- > To unsubscribe from this list: send the line "unsubscribe linux-scsi" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
