The reset_resume call is needed, otherwise it will break resume
on some conditions, depending on the usb ehci/xhci controller.
This reverts commit b89193e0b06f44f48e3bf897a5b5cb4a7aff3359.

Currently arm64 does not support PCI but it does support v4l2. Since the
PCI skeleton driver is built unconditionally as a module with no dependency
on PCI this causes build failures for arm64 allmodconfig. Fix this by
defining a symbol VIDEO_PCI_SKELETON for the skeleton and conditionalising
the build on that.

This reverts commit 747dba7de2a51a3db58b665ed3bc8c07921546ec.
It breaks concurrent vbi and video capturing:
While v4l2->users is the number of users of the whole device (all device nodes),
v4l2_fh_is_singular() only checks the number of users of a specific device node.
As a result. if one device node is open and a second device node is opened
(closed), the device is reinitialized (streaming is stopped).

When both VBI and video are streaming, and video stream is stopped,
a subsequent trial to restart it will fail, because S_FMT will
return -EBUSY.
That prevents applications like zvbi to work properly.
Please notice that, while this fix it fully for zvbi, the
best is to get rid of streaming_users and res_get logic as a hole.
However, this single-line patch is better to be merged at -stable.

The recent conversion of saa7134 to vb2 unconvered a poll() bug that
broke the teletext applications alevt and mtt. These applications
expect that calling poll() without having called VIDIOC_STREAMON will
cause poll() to return POLLERR. That did not happen in vb2.
This patch fixes that behavior. It also fixes what should happen when
poll() is called when STREAMON is called but no buffers have been
queued. In that case poll() will also return POLLERR, but only for
capture queues since output queues will always return POLLOUT
anyway in that situation.
This brings the vb2 behavior in line with the old videobuf behavior.

The v4l2_ctrl_config struct must be zeroed before passing it to
v4l2_ctrl_new_custom(). This was always wrong, but with the recent
v4l2-ctrls.c changes this is now much more likely to lead to a
kernel bug.
This is the only place where this struct wasn't initialized properly.

I traced this to a NULL i2c_adapter parent pointer when cx24123 creates its own
i2c adapter. The acpi_i2c_install_space_handler function appeared in 3.17, so
that's probably why this hasn't been seen before.

Commit bd994ddb2a12a3ff48cd549ec82cdceaea9614df (vb2: Fix stream start and
buffer completion race) broke the buffer state check in vb2_buffer_done.
So accept all three possible states there since I can no longer tell the
difference between vb2_buffer_done called from start_streaming or from
elsewhere.
Instead add a WARN_ON at the end of start_streaming that will check whether
any buffers were added to the done list, since that implies that the wrong
state was used as well.

Recently WARN_ON() calls have been added to warn if the driver is not
properly returning buffers to vb2 in start_streaming (if it fails) or
stop_streaming(). Add comments before those WARN_ON calls that refer
to the videobuf2-core.h header that explains what drivers are supposed
to do in these situations. That should help point developers in the
right direction if they see these warnings.

IT9135 RF tuner clock is coming from demodulator. We need enable it
early in demod init, before any tuner I/O. Currently it is enabled
by tuner driver itself, but it is too late and performance will be
reduced as some registers are not updated correctly. Clock is
disabled automatically when demod is put onto sleep.

We should not select SPI bus when sub-driver auto-select is
selected. That option is meant for auto-selecting all possible
ancillary drivers used for selected board driver. Ancillary
drivers should define needed dependencies itself.
I2C and I2C_MUX are still selected here for a reason described on

The sensor may be powered by either one of its sub-devices being accessed
from the user space (an open file handle) or by its s_power() op being
called with non-zero on argument. The driver counts the users and if any
reason to keep the device powered exists it will be powered.
However, a faulty condition was used in recognising the need to power off
the sensor, leading it to be powered off every time any of its uses went
away.

Pull networking updates from David Miller:
"Highlights:
1) Steady transitioning of the BPF instructure to a generic spot so
all kernel subsystems can make use of it, from Alexei Starovoitov.
2) SFC driver supports busy polling, from Alexandre Rames.
3) Take advantage of hash table in UDP multicast delivery, from David
Held.
4) Lighten locking, in particular by getting rid of the LRU lists, in
inet frag handling. From Florian Westphal.
5) Add support for various RFC6458 control messages in SCTP, from
Geir Ola Vaagland.
6) Allow to filter bridge forwarding database dumps by device, from
Jamal Hadi Salim.
7) virtio-net also now supports busy polling, from Jason Wang.
8) Some low level optimization tweaks in pktgen from Jesper Dangaard
Brouer.
9) Add support for ipv6 address generation modes, so that userland
can have some input into the process. From Jiri Pirko.
10) Consolidate common TCP connection request code in ipv4 and ipv6,
from Octavian Purdila.
11) New ARP packet logger in netfilter, from Pablo Neira Ayuso.
12) Generic resizable RCU hash table, with intial users in netlink and
nftables. From Thomas Graf.
13) Maintain a name assignment type so that userspace can see where a
network device name came from (enumerated by kernel, assigned
explicitly by userspace, etc.) From Tom Gundersen.
14) Automatic flow label generation on transmit in ipv6, from Tom
Herbert.
15) New packet timestamping facilities from Willem de Bruijn, meant to
assist in measuring latencies going into/out-of the packet
scheduler, latency from TCP data transmission to ACK, etc"

make reset control optional for i.MX27

drivers/media/platform/coda.c:3734:2: error: implicit declaration of
function 'devm_reset_control_get'
Since not all SoCs containing CODA VPUs do have a system reset controller,
use devm_reset_control_get_optional to make it optional.

Add initial support for OF based soc-camera devices that may be used
by any of the soc-camera drivers. The driver itself will need converting
to use OF.
These changes allow the soc-camera driver to do the connecting of any
async capable v4l2 device to the soc-camera driver. This has currently
been tested on the Renesas Lager board.
It currently only supports one input device per driver as this seems
to be the standard connection for these devices.
