2012-03-05brcm80211: fmac: initialize host interface drivers regardless resultArend van Spriel4-18/+8
The module init function of brcmfmac calls init functions for SDIO and USB doing driver registration. This patch removes terminating the module init when a driver registration for one host interface fails.

2012-03-05brcm80211: fmac: use counters in brcmf_bus structureArend van Spriel2-15/+4
The usb code defines a structure for counting statistics. However, it should use the statistics entry provided in brcmf_bus as that is exposed to the net_device. The usb private statistics counter only remains with counters for control packets between driver and usb device.

2012-03-05rtlwifi: rtl8192c: Prevent sleeping from invalid context in rtl8192cuLarry Finger1-3/+8
When driver rtl8192cu is used with the debug level set to 3 or greater, the result is "sleeping function called from invalid context" due to an rcu_read_lock() call in the DM refresh routine in driver rtl8192c. This lock is not necessary as the USB driver does not use the struct being protected, thus the lock is set only when a PCI interface is active.

2012-03-05rtlwifi: Remove extraneous value returnLarry Finger1-3/+2
In usb.c, routine _rtl_usb_init_sw() always returns 0, and rtl_usb_probe() never checks the returned value. Thus we can change _rtl_usb_init_sw() to a void routine.

2012-03-05cfg80211: Add an attribute to set inactivity timeout in AP modeVasanthakumar Thiagarajan3-2/+23
This patch adds an attribute, NL80211_ATTR_INACTIVITY_TIMEOUT, to set the inactivity timeout which can be used to remove the station in AP mode. This can be passed in NL80211_CMD_START_AP and used by the drivers which have AP MLME in firmware but don't support get_station() properly. To disable inactivity timer in userspace, wpa_s for example, there is a new flag, NL80211_FEATURE_INACTIVITY_TIMER, in nl80211_feature_flags through which drivers can register their capability to use the inactivity timeout to free the stations.

I've changed mwifiex_drv_change_adhoc_chan() to use a 16 bit variable. This matches the other functions in the file.

2012-03-05b43: prevent firmware on bcm5354 from taking over wrong GPIO pinsHauke Mehrtens1-0/+2
When using the bcm5354 (Soc with integrated LP-PHY Wifi) with a recent firmware >= 478.104 it runs out of memory after a very short time in OpenWrt after doing an active scan or any thing else where packages are send. This was cased by a gpio misconfiguration, the firmware triggered the GPIO pins used for buttons on some devices and that caused an other driver (OpenWrt diag) listening for these buttons irqs to send many messages to the user space. This patch fixes the bug for my devices (Asus WL-520GU) and makes it work with firmware 666.2. Now the firmware just uses LED GPIO pin number 1 and not the button pins any more.
