Hello Bing Zhao,
The patch 5e6e3a92b9a4: "wireless: mwifiex: initial commit for
Marvell mwifiex driver" from Mar 21, 2011, leads to the following
static checker warning:
drivers/net/wireless/marvell/mwifiex/sta_event.c:634
mwifiex_process_sta_event()
warn: inconsistent indenting
drivers/net/wireless/marvell/mwifiex/sta_event.c
608 case EVENT_PS_AWAKE:
609 mwifiex_dbg(adapter, EVENT, "info: EVENT: AWAKE\n");
610 if (!adapter->pps_uapsd_mode && priv->port_open &&
611 priv->media_connected &&
adapter->sleep_period.period) {
612 adapter->pps_uapsd_mode = true;
613 mwifiex_dbg(adapter, EVENT,
614 "event: PPS/UAPSD mode
activated\n");
615 }
616 adapter->tx_lock_flag = false;
617 if (adapter->pps_uapsd_mode && adapter->gen_null_pkt) {
618 if (mwifiex_check_last_packet_indication(priv))
{
619 if (adapter->data_sent ||
620 (adapter->if_ops.is_port_ready &&
621
!adapter->if_ops.is_port_ready(priv))) {
622 adapter->ps_state =
PS_STATE_AWAKE;
623 adapter->pm_wakeup_card_req =
false;
624 adapter->pm_wakeup_fw_try =
false;
625
del_timer(&adapter->wakeup_timer);
626 break;
627 }
628 if (!mwifiex_send_null_packet
629 (priv,
630
MWIFIEX_TxPD_POWER_MGMT_NULL_PACKET |
631
MWIFIEX_TxPD_POWER_MGMT_LAST_PACKET))
632 adapter->ps_state =
633 PS_STATE_SLEEP;
634 return 0;
The PS_STATE_SLEEP line is indented one tab more than it should be. It
looks like the code is buggy? Possibly curly braces were intended:
if (!mwifiex_send_null_packet(priv,
MWIFIEX_TxPD_POWER_MGMT_NULL_PACKET |
MWIFIEX_TxPD_POWER_MGMT_LAST_PACKET)) {
adapter->ps_state =
PS_STATE_SLEEP;
return 0;
}
We're right up against the 80 character limit so it's hard to be sure.
635 }
636 }
637 adapter->ps_state = PS_STATE_AWAKE;
638 adapter->pm_wakeup_card_req = false;
639 adapter->pm_wakeup_fw_try = false;
640 del_timer(&adapter->wakeup_timer);
641
642 break;
643
644 case EVENT_DEEP_SLEEP_AWAKE:
regards,
dan carpenter
