From: Julia Lawall <julia@xxxxxxx> The region set by the call to memset is immediately overwritten by the subsequent call to memcpy. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression e1,e2,e3,e4; @@ - memset(e1,e2,e3); memcpy(e1,e4,e3); // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- drivers/scsi/pm8001/pm8001_hwi.c | 1 - 1 file changed, 1 deletion(-) diff -u -p a/drivers/scsi/pm8001/pm8001_hwi.c b/drivers/scsi/pm8001/pm8001_hwi.c --- a/drivers/scsi/pm8001/pm8001_hwi.c +++ b/drivers/scsi/pm8001/pm8001_hwi.c @@ -4389,7 +4389,6 @@ pm8001_chip_fw_flash_update_req(struct p return -ENOMEM; } } - memset(buffer, 0, fw_control->len); memcpy(buffer, fw_control->buffer, fw_control->len); flash_update_info.sgl.addr = cpu_to_le64(phys_addr); flash_update_info.sgl.im_len.len = cpu_to_le32(fw_control->len); -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
