Bluetooth: Improve *_get() functions to return the object type
It's natural to have *_get() functions that increment the reference
count of an object to return the object type itself. This way it's
simple to make a copy of the object pointer and increase the reference
count in a single step. This patch updates two such get() functions,
namely hci_conn_get() and l2cap_conn_get(), and updates the users to
take advantage of the new API.

Bluetooth: Fix hci_conn reference counting for fixed channels
Now that SMP has been converted to use fixed channels we've got a bit of
a problem with the hci_conn reference counting. So far the L2CAP code
has kept a reference for each L2CAP channel that was notified of the
connection. With SMP however this would mean that the connection is
never dropped even though there are no other users of it. Furthermore,
SMP already does its own hci_conn reference counting internally,
starting from a security or pairing request and ending with the key
distribution.
This patch makes L2CAP fixed channels default to the L2CAP core not
keeping a hci_conn reference for them. A new FLAG_HOLD_HCI_CONN flag is
added so that L2CAP users can declare an exception to this rule and hold
a reference even for their fixed channels. One such exception is the
L2CAP socket layer which does want a reference for each socket (e.g. an
ATT socket which uses a fixed channel).

iwlwifi: mvm: reduce the AMPDU size in low latency mode
This allows to leave a frame in the Tx Fifo which allows
the firmware to try to enter burst mode.
The end result of this is a better latency since the
firmware utilises the TxOP better.
Also limit the AMPDU size to the limit set in the ADDBA
response. This doesn't change much since the AMPDU size
was limited by the configuration of the hardware scheduler,
but here we add a software limit by the mean of the link
quality command.

mac80211: fix chantype recalc warning
When a device driver is unloaded local->interfaces
list is cleared. If there was more than 1
interface running and connected (bound to a

ended up with compat being NULL causing a call
trace warning.
Warn if compat becomes NULL as a result of

carl9170: tx: Replace rcu_assign_pointer() with RCU_INIT_POINTER()
According to RCU_INIT_POINTER()'s block comment 3.a, it can be used if
"3. The referenced data structure has already been exposed to readers either
at compile time or via rcu_assign_pointer() -and-
a. You have not made -any- reader-visible changes to this structure since
then".
This case fulfills the conditions above because between the rcu_dereference()
call (cvif = rcu_dereference(ar->beacon_iter);) and the rcu_assign_pointer()
call there is no update of the "cvif" variable.
Therefore, this patch makes the replacement.
The following Coccinelle semantic patch was used:
@@
identifier v;
@@
v = rcu_dereference(...);
... when != rcu_dereference(...);
when != v = ...;
when != (<+...v...+>)++;
when != \(memcpy\|memset\)(...);
(
- rcu_assign_pointer
+ RCU_INIT_POINTER
(..., v);
|
if(...) {
... when != v = ...;
- rcu_assign_pointer
+ RCU_INIT_POINTER
(..., v);
... when any
}
)
Because there are cases where between a “rcu_dereference()” call and a
“rcu_assign_pointer()” call might be updates of the value that interests us,
the Coccinelle semantic patch ignores them and replaces with
"RCU_INIT_POINTER()" only when the update is not happening.

ath5k: ensure led name is null terminated
Add the missing null termination after strncpy().
This isn't actually a buffer overflow in this case since we use
snprintf() appropriately to fill the buffer passed by the caller,
but in the interest of not turning this into a bug down the road,
go ahead and force termination here.

ray_cs: Add include guards
The files ray_cs.h and rayctl.h both contain two thirds of what
appears to be an include guard using the macro name RAYLINK_H (both
lack the #define). Since RAYLINK_H is not defined anywhere, the
#ifndefs are confusing no-ops. Add proper include guards using
different macro names.

mwifiex: use firmware API revision from GET_HW_SPEC response
Newer firmware returns API revision in GET_HW_SPEC command
response. We will make use of it instead of parsing this
information from FW release number.
