When a failure to stop a module in the pipeline is detected, the only
way to recover is to reset the ISP. However, as other users can be using
a different pipeline with other modules, the ISP can't be reset
synchronously with the error detection.

Mark the ISP as needing a reset when a failure to stop a pipeline is
detected, and reset the ISP when the last user releases the last
reference to the ISP.

Modify the omap3isp_pipeline_set_stream() function to record the new ISP
pipeline state only when no error occurs, except when stopping the
pipeline in which case the pipeline is still marked as stopped.

With the introduction of CSI2 support on sh-mobile, the host driver
switched to using v4l2_device_call_until_err() with grp_id == 0 to
call subdev operations on the sensor and the CSI2 subdev. However,
this has broken multi-client set ups like the one on migor, because
that way all operations get called on both clients. To fix this add
a grp_id and set it to the client private context.

Commits 01a16b21 (netlink: kill eff_cap from struct netlink_skb_parms)
and c53fa1ed (netlink: kill loginuid/sessionid/sid members from struct
netlink_skb_parms) removed some members from struct netlink_skb_parms
that depend on the current context, all netlink users are now required
to do synchronous message processing.

connector however queues received messages and processes them in a work
queue, which is not valid anymore. This patch converts connector to do
synchronous message processing by invoking the registered callback handler
directly from the netlink receive function.

In order to avoid invoking the callback with connector locks held, a
reference count is added to struct cn_callback_entry, the reference
is taken when finding a matching callback entry on the device's queue_list
and released after the callback handler has been invoked.

This adds a driver for the CDC Ethernet part of this modem.  The
device's ID is blacklisted in cdc_ether.c and is white-listed in
this new driver because of the quirks needed to make it useful.
The modem's firmware exposes a CDC ACM port for modem control and a
CDC Ethernet port for network data.  The descriptors look fine but
both ports actually are some sort of multiplexers requiring non-
standard headers added/removed from every packet or they get
ignored.  All information is based on a usb traffic log from a
Windows machine.

On the Verizon 4G network I've seen speeds up to 1.1MB/s so far with
this driver, a speed-o-meter site reports 16.2Mbps/10.5Mbps.
Userspace scripts are required to talk to the CDC ACM port.
