Bluetooth: Fix redundant encryption request for reauthentication
When we're performing reauthentication (in order to elevate the
security level from an unauthenticated key to an authenticated one) we
do not need to issue any encryption command once authentication
completes. Since the trigger for the encryption HCI command is the
ENCRYPT_PEND flag this flag should not be set in this scenario.
Instead, the REAUTH_PEND flag takes care of all necessary steps for
reauthentication.

Bluetooth: Fix triggering BR/EDR L2CAP Connect too early
Commit
1c2e004183178 introduced an event handler for the encryption key
refresh complete event with the intent of fixing some LE/SMP cases.
However, this event is shared with BR/EDR and there we actually want to
act only on the auth_complete event (which comes after the key refresh).
If we do not do this we may trigger an L2CAP Connect Request too early
and cause the remote side to return a security block error.

Revert "Bluetooth: Enable autosuspend for Intel Bluetooth device"
This reverts commit
d2bee8fb6e18f6116aada39851918473761f7ab1.
Enabling autosuspend for Intel Bluetooth devices has been shown to not
work reliable. It does work for some people with certain combinations
of USB host controllers, but for others it puts the device to sleep and
it will not wake up for any event.
These events can be important ones like HCI Inquiry Complete or HCI
Connection Request. The events will arrive as soon as you poke the
device with a new command, but that is not something we can do in
these cases.
Initially there were patches to the xHCI USB controller that fixed
this for some people, but not for all. This could be well a problem
somewhere in the USB subsystem or in the USB host controllers or
just plain a hardware issue somewhere. At this moment we just do
not know and the only safe action is to revert this patch.

The problem is that since this commit brcmf_chip_ai_resetcore no longer sets
BCMA_IOCTL itself before bringing the core out of reset, instead relying on
brcmf_chip_ai_coredisable to do so. But brcmf_chip_ai_coredisable is a nop

to always set BCMA_IOCTL even if the core is already in reset.

ath9k: implement p2p client powersave support
Use generic TSF timers to trigger powersave state changes based
information from the P2P NoA attribute.
Opportunistic Powersave is not handled, because the driver does not
support powersave at the moment.

ray_cs: replace del_timer by del_timer_sync
Use del_timer_sync to ensure that the timer is stopped on all CPUs before
the driver exits.
This change was suggested by Thomas Gleixner.

rtl8180: be paranoid in stopping unused queues.
HW should never attempt to perform DMA for unused queues.
For rtl8187se this is ensured by setting a dedicated register at
init time, before enabling TX.
In rtl8180/5 the register is only written at the first TX (because
in rtl8180/5 it serves also to kick DMA for used queues).
This should be enough, but it's worth to add a register write at
init time, before enabling TX.

rtl8180: add parentheses to REG_ADDR macros
Parentheses are missing around the macro argument, causing the
macro possibly not to work passing certain expressions as
arguments.
This should not cause any issues with current code, however it's
worth to add them, as a good practice, and to eventually avoid
future bugs.

rtl8180: fix enabled interrupt mask for rtl8187se
When preparing the bitfield to write to HW register, the high-priority
queue error interrupt bit is set two times, and the beacon queue
TX-OK interrupt is not enabled.
Currently this have no functional impact because the high-priority
queue is not used at all, and the beacon queue is not used yet.
This patch removes high-priority queue bits and it adds the
beacon queue missing bit.
It removes also the management queue bits because it is not used.

rtl8180: change module name in rtl818x_pci
rtl8180 driver can handle also rtl8185 and rtl8187SE cards,
however in userspace tools (network manager) it still appares
as "rtl8180".
This might lead the user to think the wrong driver is in use.
This patch changes module name to "rtl818x_pci" that should be
more explanatory.
