Bluetooth: Simplify hci_conn_hold/drop logic for L2CAP
The L2CAP code has been incrementing the hci_conn reference for each
l2cap_chan instance in the l2cap_conn list. Likewise, the reference is
dropped each time an l2cap_chan is removed from the list. The reference
counting policy with respect to removal has been clear and explicit in
the l2cap_chan_del function, however for addition the function
calling 2cap_chan_add has always had to do a separate hci_conn_hold
call.
What made the counting even more hard to follow is that the
hci_connect() procedure increments the reference and the L2CAP layer
making this call took advantage of it to use it as its own reference.
This patch aims to clarify things by having the call to hci_conn_hold
inside __l2cap_chan_add, thereby removing the need to do it in the
functions calling __l2cap_chan_add. The reference count for hci_connect
is still kept as it's necessary for users such as mgmt_pair_device,

mwifiex: fix memory corruption when unsetting multicast list
When trying to unset a previously-set multicast list (i.e. the new list

mwifiex_request_set_multicast_list() while leaving
mcast_list.num_multicast_addr as an uninitialized value.

Fix this by setting mcast_list.num_multicast_addr to 0 when no multicast

wl18xx: FDSP Code RAM Corruption fix
In PG2.0 there is an issue where PHY's FDSP Code RAM sometimes gets
corrupted when exiting from ELP mode. This issue is related to FDSP
Code RAM clock implementation.
PG2.1 introduces a HW fix for this issue that requires the driver to
change the FDSP Code Ram clock settings (mux it to ATGP clock instead
of its own clock).
This workaround uses PHY_FPGA_SPARE_1 register and is relevant to WL8
PG2.1 devices.
The fix is also backward compatible with older PG2.0 devices where the
register PHY_FPGA_SPARE_1 is not used and not connected.
The fix is done in the wl18xx_pre_upload function (must be performed
before uploading the FW code) and includes the following steps:
1. Disable FDSP clock
2. Set ATPG clock toward FDSP Code RAM rather than its own clock.
3. Re-enable FDSP clock

"These are the pending NFC patches for the 3.11 merge window.
It contains the pending fixes that were on nfc-fixes (nfc-fixes-3.10-2),
along with a few more for the pn544 and pn533 drivers, the LLCP
disconnection path and an LLCP memory leak.
Highlights for this one are:
- An initial secure element API. NFC chipsets can carry an embedded
secure element or get access to the SIM one. In both cases they
control the secure elements and this API provides a way to discover,
enable and disable the available SEs. It also exports that to
userspace in order for SE focused middleware to actually do something
with them (e.g. payments).
- NCI over SPI support. SPI is the most complex NCI specified transport
layer and we now have support for it in the kernel. The next step will
be to implement drivers for NCI chipsets using this transport like
e.g. bcm2079x.
- NFC p2p hardware simulation driver. We now have an nfcsim driver that
is mostly a loopback device between 2 NFC interfaces. It also
implements the rest of the NFC core API like polling and target
detection. This driver, with neard running on top of it, allows us to
completely test the LLCP, SNEP and Handover implementation without
physical hardware.
- A Firmware update netlink API. Most (All ?) HCI chipsets have a
special firmware update mode where applications can push a new
firmware that will be flashed. We now have a netlink API for providing
that mode to e.g. nfctool."

NFC: Add secure element enablement netlink API
Enabling or disabling an NFC accessible secure element through netlink
requires giving both an NFC controller and a secure element indexes.
Once enabled the secure element will handle card emulation once polling
starts.

NFC: Add secure element enablement internal API
Called via netlink, this API will enable or disable a specific secure
element. When a secure element is enabled, it will handle card emulation
and more generically ISO-DEP target mode, i.e. all target mode cases
except for p2p target mode.

NFC: Send netlink events for secure elements additions and removals
When an NFC driver or host controller stack discovers a secure element,
it will call nfc_add_se(). In order for userspace applications to use
these secure elements, a netlink event will then be sent with the SE
index and its type. With that information userspace applications can
decide wether or not to enable SEs, through their indexes.

NFC: Add secure elements addition and removal API
This API will allow NFC drivers to add and remove the secure elements
they know about or detect. Typically this should be called (asynchronously

NFC: Extend and fix the internal secure element API
Secure elements need to be discovered after enabling the NFC controller.
This is typically done by the NCI core and the HCI drivers (HCI does not
specify how to discover SEs, it is left to the specific drivers).
Also, the SE enable/disable API explicitely takes a SE index as its
argument.

NFC: Remove the static supported_se field
Supported secure elements are typically found during a discovery process
initiated when the NFC controller is up and running. For a given NFC
chipset there can be many configurations (embedded SE or not, with or
without a SIM card wired to the NFC controller SWP interface, etc...) and
thus driver code will never know before hand which SEs are available.
So we remove this field, it will be replaced by a real SE discovery
mechanism.
