2016-09-27drm/amdgpu: don't leave dangling pointers aroundGrazvydas Ignotas
Right now it's possible to trigger fence_drv.fences[] dereference after the array has been freed. While the real problem is elsewhere, this still results in confusing errors that depend on how the freed memory was reused (I've seen "kernel tried to execute NX-protected page"), it's better to clear them and get NULL dereference so that it's obvious what's going wrong.

2016-09-27brcmfmac: use correct skb freeing helper when deleting flowringRafał Miłecki
Flowrings contain skbs waiting for transmission that were passed to us by netif. It means we checked every one of them looking for 802.1x Ethernet type. When deleting flowring we have to use freeing function that will check for 802.1x type as well. Freeing skbs without a proper check was leading to counter not being properly decreased. This was triggering a WARNING every time brcmf_netdev_wait_pend8021x was called.

2016-09-27brcmfmac: replace WARNING on timeout with a simple error messageRafał Miłecki
Even with timeout increased to 950 ms we get WARNINGs from time to time. It mostly happens on A-MPDU stalls (e.g. when station goes out of range). It may take up to 5-10 secods for the firmware to recover and for that time it doesn't process packets. It's still useful to have a message on time out as it may indicate some firmware problem and incorrect key update. Raising a WARNING however wasn't really that necessary, it doesn't point to any driver bug anymore and backtrace wasn't much useful.

Issue reproduction procedure: 1. three or more fingers put on Touchpad. 2. release fingers from Touchpad. 3. move the cursor by one finger. 4. the cursor does not move. Cause: We do not notify multi fingers state correctly to input subsystem. For example, when three fingers release from Touchpad, fingers state is 3 -> 0. It needs to notify first, second and third finger's releasing state. Fix this by not breaking out on z axis and move x,y,z input handling code to the correct place so that it's in fact per-finger.
