Pull char/misc driver updates from Greg KH:
"Here's the big char/misc driver patches for 4.10-rc1. Lots of tiny
changes over lots of "minor" driver subsystems, the largest being some
new FPGA drivers. Other than that, a few other new drivers, but no new
driver subsystems added for this kernel cycle, a nice change.
All of these have been in linux-next with no reported issues"

We found network manager is necessary on RHEL to make the synthetic
NIC, VF NIC bonding operations handled automatically. So, enabling
network manager here.

Hyper-V host will send a VSS_OP_HOT_BACKUP request to check if guest is
ready for a live backup/snapshot. The driver should respond to the check
only if the daemon is running and listening to requests. This allows the
host to fallback to standard snapshots in case the VSS daemon is not
running.

KVP daemon does fork()/exec() (with popen()) so we need to close our fds
to avoid sharing them with child processes. The immediate implication of
not doing so I see is SELinux complaining about 'ip' trying to access
'/dev/vmbus/hv_kvp'.

This script helps to create bonding network devices based on synthetic NIC
(the virtual network adapter usually provided by Hyper-V) and the matching
VF NIC (SRIOV virtual function). So the synthetic NIC and VF NIC can
function as one network device, and fail over to the synthetic NIC if VF is
down.
Mayjor distros (RHEL, Ubuntu, SLES) supported by Hyper-V are supported by
this script.

By default lsvmbus lists all the devices in the VMBus.
With -v or -vv, more information is printed, including the VMBus
Rel_ID, class ID, device ID and which channel is bound to which

fwrite() does not actually return the number of bytes written and
this value is being ignored anyway and ferror() is being called to
check for an error. As we assign to this variable and never use it
we get the following compile-time warning:
hv_kvp_daemon.c:149:9: warning: variable .bytes_written. set but not used [-Wunused-but-set-variable]
Remove bytes_written completely.
