4596fde540 Bluetooth: mgmt: Fix address type while loading Long Term Key
This patch fixes the address type while loading long term keys when BT is
switched on. Without this fix pairing is reinitated even though LTK
exists for remote device because of mismatch of address type.

The function already fails if the given size is greater than the MTU, so
there is no need to consider that case afterwards.

abc5de8f4e Bluetooth: Use unsigned int instead of signed int
The involved values are all unsigned and thus unsigned int should be
used instead of signed int. Assigning ~0 to a signed int results in -1,
which is confusing and error-prone, while the code is trying to set the
maximum value possible.

The code still works because the C standard defines that unsigned
comparison will be performed in these cases, when comparing an unsigned
int and a signed int.

3c588192b5 Bluetooth: Add the l2cap_seq_list structure for tracking frames
A sequence list is a data structure used to track frames that need to
be retransmitted, and frames that have been requested for
retransmission by the remote device.  It can compactly represent a
list of sequence numbers within the ERTM transmit window.  Memory for
the list is allocated once at connection time, and common operations
in ERTM are O(1).

b24c62471c Bluetooth: Fix clearing discovery type when stopping discovery
This patch prevents resetting of discovery type while stopping
discovery, since otherwise the wrong type might be send in case of
discovery failure. It also doesn't matter that we are "lazy" with
updating the type since it is anyway reset when starting discovery again
and it's not needed to know the current discovery state.

0dea0141a9 Bluetooth: vhci: Ignore return code of nonseekable_open()
The comment in ./fs/open.c clearly states that nonseekable_open() will
never fail. Therefore, we can safely ignore the return code. This is the
recommended way to deal with nonseekable_open().
Our current code looks like nonseekable_open() is checked for the return
code. However, if we check the return code, we must also kfree() our
private data if the open fails. To avoid this overhead and to avoid
confusion, we simply drop the return code and return 0.

053262dce5 Bluetooth: Update management interface revision
For each kernel release where commands or events are added to the
management interface, the revision field should be increment by one.

The increment should only happen once per kernel release and not
for every command/event that gets added. The revision value is for
informational purposes only, but this simple policy would make any
future debugging a lot simple.
