This function returns a referenced BSS struct

that a lot of drivers get this completely wrong

802.11n-2009 extends the supported rates element with a
magic value which can be used to prevent legacy stations
from joining the BSS.
However, this magic value is not a rate like the others
and the magic can simply be ignored/skipped at this late
stage.

This patch moves the pending management command list (previously global
to mgmt.c) into struct hci_dev. This makes it possible to do proper
locking when accessing it (through the existing hci_dev locks) and
thereby avoid race conditions.

The current global pending command list in mgmt.c is racy. Possibly the
simplest way to fix it is to have per-hci dev lists instead of a global
one (all commands that need a pending struct are hci_dev specific).
This way the list can be protected using the already existing per-hci
dev lock. To enable this refactoring the first thing that needs to be
done is to ensure that the mgmt functions have access to the hci_dev
struct (instead of just the dev id).

This patch adds a function to hci_core to cancel an ongoing inquiry.
According to the Bluetooth spec, the inquiry cancel command should
only be issued after the inquiry command has been issued, a command
status event has been received for the inquiry command, and before
the inquiry complete event occurs.
As HCI_INQUIRY flag is only set just after an inquiry command status
event occurs and it is cleared just after an inquiry complete event
occurs, the inquiry cancel command should be issued only if HCI_INQUIRY
flag is set.
Additionally, cancel inquiry related code from stop_discovery() were
replaced by a hci_cancel_inquiry() call.

* git://github.com/rustyrussell/linux:
params: make dashes and underscores in parameter names truly equal
kmod: prevent kmod_loop_msg overflow in __request_module()
* 'for-linus' of git://github.com/ericvh/linux:
9p: fix 9p.txt to advertise msize instead of maxdata
net/9p: Convert net/9p protocol dumps to tracepoints
fs/9p: change an int to unsigned int
fs/9p: Cleanup option parsing in 9p

fs/9p: Update zero-copy implementation in 9p
The user may use "foo-bar" for a kernel parameter defined as "foo_bar".
Make sure it works the other way around too.
Apply the equality of dashes and underscores on early_params and __setup
params as well.
The example given in Documentation/kernel-parameters.txt indicates that
this is the intended behaviour.
With the patch the kernel accepts "log-buf-len=1M" as expected.
