2011-05-13wl12xx: prevent scheduling while suspending (WoW enabled)Eliad Peller
When WoW is enabled, the interface will stay up and the chip will be powered on, so we have to flush/cancel any remaining work, and prevent the irq handler from scheduling a new work until the system is resumed. Add 2 new flags: * WL1271_FLAG_SUSPENDED - the system is (about to be) suspended. * WL1271_FLAG_PENDING_WORK - there is a pending irq work which should be scheduled when the system is being resumed. In order to wake-up the system while getting an irq, we initialize the device as wakeup device, and calling pm_wakeup_event() upon getting the interrupt (while the system is about to be suspended) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2011-05-10mwifiex: remove unnecessary struct mwifiex_opt_sleep_confirm_bufferAmitkumar Karwar
The structure definition is struct mwifiex_opt_sleep_confirm_buffer { u8 hdr[4]; struct mwifiex_opt_sleep_confirm ps_cfm_sleep; } __packed; For sleep_confirm command we already reserve 4 bytes (using skb_reserve()) for an interface header. It will be filled later by interface specific code. We don't need "hdr[4]" element in above structure.

2011-05-10iwlagn: fix iwl_is_any_associatedJohannes Berg
The function iwl_is_any_associated() was intended to check both contexts, but due to an oversight it only checks the BSS context. This leads to a problem with scanning since the passive dwell time isn't restricted appropriately and a scan that includes passive channels will never finish if only the PAN context is associated since the default dwell time of 120ms won't fit into the normal 100 TU DTIM interval. Fix the function by using for_each_context() and also reorganise the other functions a bit to take advantage of each other making the code easier to read.
