Use del_timer_sync() instead of del_timer() as this ensures that rfcomm_session_timeout() is not running on a different CPU when rfcomm_session_put() is called. This avoids a race condition on SMP systems because potentially rfcomm_session_timeout() could reuse the freed RFCOMM session structure caused by the execution of rfcomm_session_put(). Note that this modification makes the reason for the RFCOMM session refcnt mechanism redundant. Signed-off-by:

There is no reason a caller ever wants to check the return type of this call. _Iff_ a user successfully called bt_sock_register(), they're allowed to call bt_sock_unregister(). All other calls in the kernel (device_del, device_unregister, kfree(), ..) that are logically equivalent return void. Lets not make callers think they have to check the return type of this call and instead simply return void. We guarantee that after bt_sock_unregister() is called, the socket type _is_ unregistered. If that is not what the caller wants, they're using the wrong function, anyway. Signed-off-by:

After we successfully registered a socket via bt_sock_register() there is no reason to ever check the return code of bt_sock_unregister(). If bt_sock_unregister() fails, it means the socket _is_ already unregistered so we have what we want, don't we? Also, to get bt_sock_unregister() to fail, another part of the kernel has to unregister _our_ socket. This is sooo _wrong_ that it will break way earlier than when we unregister our socket.

After linux 3.2 the hid_destroy_device call in hidp_session cleaning up invokes a hook to the power_supply code which in turn tries to read the battery capacity. This read will trigger a call to hidp_get_raw_report which is bound to fail because the device is being taken away - so rather than wait for the 5 second timeout failure this changes enables it to fail straight away.

Currently 'magic-packet' and 'patterns' options in 'iw wowlan' command are supported. Appropriate packet filters for wowlan are configured in firmware based on provided patterns and/or magic-packet option.

We allocate SKB buffers of 4K size to make sure that we process RX AMSDU of 4K. So when skb->len is lesser than 4K; we should modify skb->truesize. This resolves an issue where kernel has allocated packets with 2K assumption and starts dropping packets for large size data transfer. This fix is already present for USB; extend it to PCIE.

HT-PHY was found only on BCM4331 which is a BCMA-based chipset. This is reallly unlikely we will ever see HT-PHY on SSB thus make the whole code BCMA specific. This will allow us to call various BCMA-specific functions directly (without extra checks). Signed-off-by:

The function brcmf_proto_hdrpush() increases the header space and fills in the protocol header fields. One field is the data offset which is currently fixed to zero meaning the data follows right after the header. The parameter is added to determine the actual start of data. This will be used for firmware signalling. Reviewed-by:

"translate" should either be set or disabled. We also use it an offset into the framing[] array when we're generating the proc file. Framing looks like this: static const char *framing[] = { "Encapsulation", "Translation" } So when we're setting translate we need to restrict the values to either 1 or 0 or it can an out of bounds read.
