As most LE devices leave advertising mode when they enter the connected
state, we may want to "pass" that connection to other users.
The first user will be the pairing procedure, the connection is
established without an associated socket, after the pairing is
complete, userspace may want to discover via GATT what services the
newly bonded device has.
If userspace establishes the connection while the timeout still

We currently initialize locks, lists, works, etc. in hci_register_dev()
(hci_alloc_dev() was added later) which is bogus because an hdev is in an
invalid state if it is not registered.
This patch moves all memory initialization to hci_alloc_dev(). Device
registering and registration of sub-modules is still left in
hci_register_dev() as it belongs there.
The benefit is (despite cleaning up the code-base) we can now always be
sure that an hdev is a valid object and can be locked and worked on even
though it may not be registered.
This patch also reorders the initialization to be easier to understand.
First the memory is initialized, then all generic structures and as last
step the sub-init functions are called. This guarantees that all
dependencies are initialized in the right order and makes it also easier
to find a specific line. We previously initialized it in the same order as
the "struct hci_dev" is declared which seems pretty random.

We assume id starts with the number we'll try to add the new device

is we start with 0 for BR/EDR device and 1 for AMP devices (thus AMP
devices will never receive register as index 0). Then every hdev->id in
the _ordered_ list <= to the id we want we increment id and move the
variable head. In the end we'll have id as the first available one and

All num, magic and owner are set by alloc_tty_driver. No need to
re-set them on each allocation site.
pti driver sets something different to what it passes to
alloc_tty_driver. It is not a bug, since we don't use the lines
parameter in any way. Anyway this is fixed, and now we do the right
thing.

If a master would like to raise the security level, it will send a
pairing request. While the pending security level is set on an incoming
security request (from a slave), it is not set on a pairing request. As
a result, the security level would not be raised on the slave in such
case.
Fix this by setting the pending security when receiving pairing
requests according to the requested authorization.

The major index of the table is actually the remote I/O capabilities, not
the local ones. As a result, devices with different I/O capabilities
could have used wrong or even unsupported generation methods.
