platform_device_unregister() only calls platform_device_del() and platform_device_put(), thus use platform_device_unregister() to simplify the code. Also the documents in platform.c shows that platform_device_del and platform_device_put must _only_ be externally called in error cases. All other usage is a bug. dpatch engine is used to auto generate this patch. (https://github.com/weiyj/dpatch) Signed-off-by:

The function wl12xx_set_power_on is only called twice, once in wl12xx_chip_wakeup and once in wl12xx_get_hw_info. On the failure of the call in wl12xx_chip_wakeup, the containing function just returns, but on the failure of the call in wl12xx_get_hw_info, the containing function calls wl1271_power_off. This does not seem necessary, because if wl12xx_set_power_on has set the power on and then fails, it has already turned the power off. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier f,free,a; parameter list[n] ps; type T; expression e; @@ f(ps,T a,...) { ... when any when != a = e if(...) { ... free(a); ... return ...; } ... when any } @@ identifier r.f,r.free; expression x,a; expression list[r.n] xs; @@ * x = f(xs,a,...); if (...) { ... free(a); ... return ...; } // </smpl> Signed-off-by:

Set tx packet timestamp to 0 in following scenarios:- - All packets in STA mode - Mgmt packets in AP mode - Eapol packets in AP mode In STA mode, this field is unused in the firmware. In AP mode, we should not be expiring mgmt and eapol frames. Setting timestamp to 0 will ensure that. Signed-off-by:

We have 6.5 Mbps is minimum rate of the link as the criterion for creation of BA. Although we check this before creating the BA stream, by the time amdpu_action is called from the workqueue, the link can get affected in the meantime. Hence, add an additional check in amdpu_action. Signed-off-by:

ksdioirqd has higher priority than kworker. Process RX packets in SDIO IRQ thread (ksdioirqd/mmcX) directly instead of deferring the work to kworker to avoid the extra latency. This improves TCP throughput 15~20% on an ARM platform with SDIO 2.0 controller. Signed-off-by:

Firmware events are passed to wl_cfg80211 module associated with the primary net device. With virtual interface support events can be received for different interfaces, ie. struct brcmf_if instances. Pass it in the event to determine appropriate net device associated with the event. Reviewed-by:

The function brcmf_fil_bsscfg_data_get() calls brcmf_create_iovar() with data pointer set to NULL, which caused a NULL pointer access. As it should be possible to provide data in message towards the firmware, it should just pass the data buffer instead. Reviewed-by:

The function brcmf_set_management_ie() operates on virtual interface data and brcmf_cfg80211_vif structure provides all information needed for interfacing with firmware. As this function will also be needed for interface without an associated net device it makes sense to provide the vif instead of deriving it from the net device. Reviewed-by:

The function brcmf_inform_bss() validates the version received from the device, before processing the individual bss entries. This error condition is only applicable when the list contains entries. A specific scan, ie. for a specific ssid, can result in a scan completion without finding any bss entries. No need to flag it as an error in the log when this happens. Reviewed-by:

This patch adds support for multiple TX queues inside mwifiex driver. Four different queues according to WMM access categories are defined for each virtual interface. When a packet is received from netdev for transmission, tx pending count for particular queue is incremented and if tx pending count has reached upper water-mark, this queue is stopped instead of stopping all queues. Similarly when a packet is successfully transmitted from device, tx pending count is decremented per queue and if pending count falls below lower water-mark, queue operations are again resumed. This ensures that not all tranmission is blocked if traffic with particular TOS value suddenly increases. Also wake all queues after association/IBSS_join/uAP_BSS_start to enable traffic on all queues. Signed-off-by:

When command timeout happens due to a bug in firmware/hardware, the timeout handler just prints some debug information. User is unable to reload the driver in this case. Inspired by 9a821f5d "libertas: add sd8686 reset_card support", this patch adds card reset support for SDIO interface when command timeout happens. If the SDIO host contoller supports MMC_POWER_OFF|UP|ON operations, the chip will be reset and the firmware will be re-downloaded. Signed-off-by:
