drv->st_register_cb_status = -EINPROGRESS;
There are actually two issues:
1. Whether "char" is signed or unsigned depends on the architecture.
As the completion callback data is used to pass a (negative) error
code, it should always be signed.
2. EINPROGRESS is 150 on mips, 245 on parisc.
Hence -EINPROGRESS doesn't fit in a signed 8-bit number.
Change the callback status from "char" to "int" to fix these.

A deadlock can occur when the NFC raw socket is closed while

Following is the call graph of the affected situation:
send data via raw_sock:
-------------
rawsock_tx_work
sock_hold => socket refcnt++
nfc_data_exchange => cb = rawsock_data_exchange_complete
ops->im_transceive = pn533_transceive => arg->cb = db
= rawsock_data_exchange_complete
pn533_send_data_async => cb = pn533_data_exchange_complete
__pn533_send_async => cmd->complete_cb = cb
= pn533_data_exchange_complete
if_ops->send_frame_async
response:
--------
pn533_recv_response
queue_work(priv->wq, &priv->cmd_complete_work)
pn533_wq_cmd_complete
pn533_send_async_complete
cmd->complete_cb() = pn533_data_exchange_complete()
arg->cb() = rawsock_data_exchange_complete()
sock_put => socket refcnt-- => If the corresponding
socket gets closed in the meantime socket
will be destructed
sk_free
__sk_free
sk->sk_destruct = rawsock_destruct
nfc_deactivate_target
ops->deactivate_target = pn533_deactivate_target
pn533_send_cmd_sync
pn533_send_cmd_async
__pn533_send_async
list_add_tail(&cmd->queue,&dev->cmd_queue)
=> add to command list because
a command is currently
processed
wait_for_completion
=> the workqueue thread waits
here because it is the one
processing the commands
=> deadlock
To fix the deadlock pn533_deactivate_target is changed to
issue the PN533_CMD_IN_RELEASE command in async mode. This
way nothing blocks and the release command is executed after
the current command.

Currently it is not possible to only poll for passive targets
with the pn533 driver. To change this ATR_REQ is only sent when
NFC_PROTO_NFC_DEP is explicitly requested in poll_protocols.
As most implementations (e.g. neard) poll for all protocols
that are reported to be supported by the adapter, this should
not have much of an effect on current implementations.

Pull networking updates from David Miller:
"Highlights:
1) Support more Realtek wireless chips, from Jes Sorenson.
2) New BPF types for per-cpu hash and arrap maps, from Alexei
Starovoitov.
3) Make several TCP sysctls per-namespace, from Nikolay Borisov.
4) Allow the use of SO_REUSEPORT in order to do per-thread processing
of incoming TCP/UDP connections. The muxing can be done using a
BPF program which hashes the incoming packet. From Craig Gallek.
5) Add a multiplexer for TCP streams, to provide a messaged based
interface. BPF programs can be used to determine the message
boundaries. From Tom Herbert.
6) Add 802.1AE MACSEC support, from Sabrina Dubroca.
7) Avoid factorial complexity when taking down an inetdev interface
with lots of configured addresses. We were doing things like
traversing the entire address less for each address removed, and
flushing the entire netfilter conntrack table for every address as
well.
8) Add and use SKB bulk free infrastructure, from Jesper Brouer.
9) Allow offloading u32 classifiers to hardware, and implement for
ixgbe, from John Fastabend.
10) Allow configuring IRQ coalescing parameters on a per-queue basis,
from Kan Liang.
11) Extend ethtool so that larger link mode masks can be supported.
From David Decotigny.
12) Introduce devlink, which can be used to configure port link types
(ethernet vs Infiniband, etc.), port splitting, and switch device
level attributes as a whole. From Jiri Pirko.
13) Hardware offload support for flower classifiers, from Amir Vadai.
14) Add "Local Checksum Offload". Basically, for a tunneled packet
the checksum of the outer header is 'constant' (because with the
checksum field filled into the inner protocol header, the payload
of the outer frame checksums to 'zero'), and we can take advantage
of that in various ways. From Edward Cree"
