The commit 42624d49 created following sparse warning >net/mac80211/sta_info.c:965:24: warning: incorrect type in assignment (different address spaces) >net/mac80211/sta_info.c:965:24: expected struct tid_ampdu_tx *tid_tx >net/mac80211/sta_info.c:965:24: got struct tid_ampdu_tx [noderef] <asn:4>*<noident> Making use of rcu_dereference_protected to fix the problem. V2: - Replacing rcu_dereference with rcu_dereference_protected as suggested by Johannes. - Adding mutex_lock/unlock to satisfy the condition at rcu_dereference_protected Cc: Nishant Sarmukadam <nishants@marvell.com> Reported-by:

The commit "ath9k: simplify tx locking" introduced a soft lockup triggered by mac80211 sending a BAR frame triggered by a driver call to ieee80211_tx_send_bar or ieee80211_tx_status. Fix these issues by queueing processed tx status skbs and submitting them to mac80211 outside of the lock. Signed-off-by:

Many systems (e.g. embedded systems) do not have wifi modules connected to bluetooth modules, so bluetooth coexistence is irrelevant there. With the addition of MCI support, ath9k picked up quite a bit of extra code that can be compiled out this way. This patch redefines ATH9K_HW_CAP_MCI and adds an inline wrapper for querying the bluetooth coexistence scheme, allowing the compiler to eliminate code that uses it, with only very little use of #ifdef. On MIPS this reduces the total size for the modules by about 20k. Signed-off-by:

When I tested commit 6539306b, I did not notice that loading an out-of-tree module turns off lockdep testing in kernel 3.2. For that reason, I missed the kernel WARNING shown below: The solution fixes the warning by partially reverting commit 6539306b.

When there is data available in dongle for driver to fetch, an interrupt will be triggered and both SDIO function 1 and 2 will be flagged by default in bcm4329. These two interrupt flags are identical and only need to be handled once. Since there is no way to turn off one flag from the dongle side, a dummy handler for function 2 interrupt is placed.
