In commit a5ffbe0, some of the calls to rtl_lps_leave() were switched to be called from a work queue to avoid a scheduling while atomic bug. This patch converts the remaining calls to use the work queue. In addition, the call to rtl_lps_enter() is also switched to the work queue. None of these newly converted calls had triggered the bug (yet), but this change make all of them fit a single pattern.

2013-02-18rtlwifi: usb: allocate URB control message setup_packet and data buffer ↵Jussi Kivilinna1-16/+28
separately rtlwifi allocates both setup_packet and data buffer of control message urb, using shared kmalloc in _usbctrl_vendorreq_async_write. Structure used for allocating is: struct { u8 data[254]; struct usb_ctrlrequest dr; }; Because 'struct usb_ctrlrequest' is __packed, setup packet is unaligned and DMA mapping of both 'data' and 'dr' confuses ARM/sunxi, leading to memory corruptions and freezes.

2013-02-15mac80211: stop toggling IEEE80211_HT_CAP_SUP_WIDTH_20_40Johannes Berg10-24/+15
For VHT, many more bandwidth changes are possible. As a first step, stop toggling the IEEE80211_HT_CAP_SUP_WIDTH_20_40 flag in the HT capabilities and instead introduce a bandwidth field indicating the currently usable bandwidth to transmit to the station. Of course, make all drivers use it. To achieve this, make ieee80211_ht_cap_ie_to_sta_ht_cap() get the station as an argument, rather than the new capabilities, so it can set up the new bandwidth field. If the station is a VHT station and VHT bandwidth is in use, also set the bandwidth accordingly. Doing this allows us to get rid of the supports_40mhz flag as the HT capabilities now reflect the true capability instead of the current setting. While at it, also fix ieee80211_ht_cap_ie_to_sta_ht_cap() to not ignore HT cap overrides when MCS TX isn't supported (not that it really happens...) Signed-off-by: Johannes Berg <[email protected]>

This partially reverts commit 44ba973699b831414c3f8eef68ee5a7fe1208a05. rate_control_rate_init assumes the rate_init member of struct rate_control_ops is not NULL therefore not initializing it leads to an oops as soon the driver succesfully associates to an AP. The removal of rate_update from 44ba973699b831414c3f8eef68ee5a7fe1208a05 is ok because rate_update is checked for NULL before being called.
