Fixed up some trivial conflicts in the staging tree, due to the fwserial
driver having come in both ways (but fixed up a bit in the serial tree),
and the ioctl handling in the dgrp driver having been done slightly
differently (staging tree got that one right, and removed both
TIOCGSOFTCAR and TIOCSSOFTCAR).

This patch fixes a bug introduced in bbd9f9e which could prevent
some wakeups from working correctly if multiple wol options were
selected.

This helper function calculates a 16-bit crc and shifts it into
either the high or low 16 bits of a u32 so the caller can or it
directly into place.  The function previously had a u16 return
type so would always have returned zero when filter was odd.

Jiri Slaby 191c5f1027 TTY: call tty_port_destroy in the rest of drivers
After commit "TTY: move tty buffers to tty_port", the tty buffers are
not freed in some drivers. This is because tty_port_destructor is not
called whenever a tty_port is freed. This was an assumption I counted
with but was unfortunately untrue. So fix the drivers to fulfil this
assumption.

To be sure, the TTY buffers (and later some stuff) are gone along with
the tty_port, we have to call tty_port_destroy at tear-down places.
This is mostly where the structure containing a tty_port is freed.
This patch does exactly that -- put tty_port_destroy at those places.

Bjørn Mork bbc8d9228e net: cdc_ncm: add Huawei devices
A number of Huawei 3G and LTE modems implement a CDC NCM function,
including the necessary functional descriptors, but using a non
standard interface layout and class/subclass/protocol codes.

These devices can be handled by this driver with only a minor
change to the probing logic, allowing a single combined control
and data interface.  This works because the devices
- include a CDC Union descriptor labelling the combined
  interface as both master and slave, and
- have an alternate setting #1 for the bulk endpoints on the
  combined interface.

The 3G/LTE network connection is managed by vendor specific AT
commands on a serial function in the same composite device.
Handling the managment function is out of the scope of this
driver.  It will be handled by an appropriate USB serial
driver.

Steve Glendinning 9532021da6 usbnet: ratelimit kevent may have been dropped warnings
when something goes wrong, a flood of these messages can be
generated by usbnet (thousands per second).  This doesn't
generally *help* the condition so this patch ratelimits the
rate of their generation.

There's an underlying problem in usbnet's kevent deferral
mechanism which needs fixing, specifically that events *can*
get dropped and not handled.  This patch doesn't address this,
but just mitigates fallout caused by the current implemention.

Ian Coolidge a66fe1653f net: usb: cdc_eem: Fix rx skb allocation for 802.1Q VLANs
cdc_eem frames might need to contain 802.1Q VLAN Ethernet frames.
URB/skb sizing from usbnet will default to the hard_mtu,
so account for the VLAN header by expanding that via hard_header_len

Ming Lei 6f0a0986e3 usbnet: runtime wake up device before calling usbnet_{read|write}_cmd
This patch gets the runtime PM reference count before calling
usbnet_{read|write}_cmd, and puts it after completion of the
usbnet_{read|write}_cmd, so that the usb control message can always
be sent to one active device in the non-PM context.

Ming Lei ec32115db2 usbnet: smsc95xx: apply the introduced usbnet_{read|write}_cmd_nopm
This patch applies the introduced usbnet_read_cmd_nopm() and
usbnet_write_cmd_nopm() in the callback of resume and suspend
to avoid deadlock if USB runtime PM is considered into
usbnet_read_cmd() and usbnet_write_cmd().

Ming Lei 06a221be02 usbnet: smsc95xx: fix memory leak in smsc95xx_suspend
This patch fixes memory leak in smsc95xx_suspend.

Also, it isn't necessary to bother mm to allocate 8bytes/16byte,
and we can use stack variable safely.

Ming Lei 0547fad2dd usbnet: introduce usbnet_{read|write}_cmd_nopm
This patch introduces the below two helpers to prepare for solving
the usbnet runtime PM problem, which may cause some network utilities
(ifconfig, ethtool,...) touch a suspended device.

	usbnet_read_cmd_nopm()
	usbnet_write_cmd_nopm()

The above two helpers should be called by usbnet resume/suspend
callback to avoid deadlock.

Steve Glendinning 00acda68b5 smsc95xx: fix tx checksum offload for big endian
f7b2927 introduced tx checksum offload support for smsc95xx,
and enabled it by default. This feature doesn't take
endianness into account, so causes most tx to fail on
those platforms.

This patch fixes the problem fully by adding the missing
conversion.

An alternate workaround is to disable TX checksum offload
on those platforms. The cpu impact of this feature is very low.
