Jeff Kirsher 98b32decc8 nfc: Fix FSF address in file headers
Several files refer to an old address for the Free Software Foundation
in the file header comment.  Resolve by replacing the address with
the URL <http://www.gnu.org/licenses/> so that we do not have to keep
updating the header comments anytime the address changes.

Eric Lapuyade bf71ab8ba5 NFC: Add HCI quirks to support driver (non)standard implementations
Some chips diverge from the HCI spec in their implementation of standard
features. This adds a new quirks parameter to
nfc_hci_allocate_device() to let the driver indicate its divergence.

Eric Lapuyade 07887e9220 NFC: Fix hci_connect_gate() when a pre-opened pipe is passed
In some cases, pre-opened pipes don't stay open when a clear all pipes
command is sent. They stay created however. Therefore, one can never
assume that such a pipe is already open. As re-opening a pipe seems not
to be a problem, we do that now.

Szymon Janc 0250ffc578 NFC: Fix not propagating return code in nfc_hci_clear_all_pipes
Return code from nfc_hci_execute_cmd was not propagated to caller.

Szymon Janc 80e4232ecb NFC: Small nfc_hci_create_pipe refactoring
Check for error and return if any. This makes it easier to see what is
a 'positive' function flow.

Eric Lapuyade e4c4789e55 NFC: Add a public nfc_hci_send_cmd_async method
This method initiates execution of an HCI cmd. Result will be delivered
through an asynchronous callback.

Eric Lapuyade b5faa648fa NFC: Changed the HCI cmd execution callback prototype
Make it match the data_exchange_cb_t so that it can be used directly in
the implementation of an asynchronous hci_transceive

Eric Lapuyade a10d595b10 NFC: Allow HCI driver to pre-open pipes to some gates
Some NFC chips will statically create and open pipes for both standard
and proprietary gates. The driver can now pass this information to HCI
such that HCI will not attempt to create and open them, but will instead
directly use the passed pipe ids.

Eric Lapuyade 6c1c5b9e1d NFC: Changed HCI cmd execution completion result to std linux errno
An HCI command can complete either from an HCI response
(with an HCI result) or as a consequence of any other system
error during processing. The completion therefore needs to take
a standard errno code. The HCI response will convert its result
to a standard errno before calling the completion.

Eric Lapuyade 8b8d2e08bf NFC: HCI support
This is an implementation of ETSI TS 102 622 specification.
Many NFC chipsets use HCI as the host <-> target protocol on top of a
serial link like i2c.
