Adds support for the Plextor ConvertX PX-AV100U, which uses the
eMPIA EM2820 chip. The device has a device_id of '0x093b, 0xa003'. I
am using the existing EM2820_BOARD_PINNACLE_DVC_90 board profile, as
the Pinnacle Dazzle DVC 90/100/101/107, Kaiser Baas Video to DVD

The VIDIOC_LOG_STATUS ioctl allows to dump the current status of a driver
to the kernel log. Currently this ioctl is only available at video device
nodes and the subdevs rely on the host driver to expose their core.log_status
operation to user space.
This patch adds VIDIOC_LOG_STATUS support at the sub-device nodes,
for standalone subdevs that expose their own /dev entry.

The following ioctl sequence causes fimc_dma_run() to start processing without
complete scaler and DMA initialization which causes missing interrupt and
blocking on DQBUF:
S_FMT, STREAMON, QBUF, DQBUF, STREAMOFF, STREAMON, QBUF, DQBUF.
Fix this regression caused by moving pm_runtime* calls to start/stop_streaming
callback by making sure the fimc_m2m_resume() is always invoked when expected.

When reading RAID5 files, in rare cases, we calculated too
few sg segments. There should be two extra for the beginning
and end partial units.
Also "too few sg segments" should not be a BUG_ON there is
all the mechanics in place to handle it, as a short read.
So just return -ENOMEM and the rest of the code will gracefully
split the IO.

As Reported by Randy Dunlap
When MISC_FILESYSTEMS is not enabled and NFS4.1 is:
fs/built-in.o: In function `objio_alloc_io_state':
objio_osd.c:(.text+0xcb525): undefined reference to `ore_get_rw_state'

objio_osd.c:(.text+0xcb58d): undefined reference to `ore_check_io'
fs/built-in.o: In function `_read_done':
...
When MISC_FILESYSTEMS, which is more of a GUI thing then anything else,
is not selected. exofs/Kconfig is never examined during Kconfig,
and it can not do it's magic stuff to automatically select everything
needed.
We must split exofs/Kconfig in two. The ore one is always included.
And the exofs one is left in it's old place in the menu.

Repeating the same cleanup code in each error handling path makes life
unnecessarily difficult for reviewers, who much check each instance of
the same copy+pasted code separately. A "goto" to the end of the

While we're touching this code, also lift some assignments from "if"
conditionals for simplicity.

videobuf_dvb_register_bus relies on dvb_net_init to set dvbnet->dvbdev
on success, but ever since commit fcc8e7d8c0e2 ("dvb_net: Simplify the
code if DVB NET is not defined"), ->dvbdev is left unset when
networking support is disabled. Therefore in such configurations
videobuf_dvb_register_bus always returns failure, tripping
little-tested error handling paths and preventing the device from
being initialized and used.
Now that dvb_net_init returns a nonzero value on error, we can use
that as a more reliable error indication. Do so.
Now your card be used with CONFIG_DVB_NET=n, and the kernel will pass
on a more useful error code describing what happened when
CONFIG_DVB_NET=y but dvb_net_init fails due to resource exhaustion.

dvb_net_init unconditionally returns 0. Callers such as
videobuf_dvb_register_frontend examine dvbnet->dvbdev instead of the
return value to tell whether the operation succeeded. If it has been
set to a valid pointer, success; if it was left equal to NULL,
failure.
Alas, there is an edge case where that logic does not work as well:
when network support has been compiled out (CONFIG_DVB_NET=n), we want
dvb_net_init and related operations to behave as no-ops and always
succeed, but there is no appropriate value to which to set dvb->dvbdev
to indicate this.
Let dvb_net_init return a meaningful error code, as preparation for
adapting callers to look at that instead.
The only immediate impact of this patch should be to make the few
callers that already check for an error code from dvb_net_init behave
a little more sensibly when it fails.

We have no business doing any this in the standard write release path.
Get rid of it, and put it in the pNFS layer.
Also, while we're at it, get rid of the completely bogus unlock/relock
semantics that were present in nfs_writeback_release_full(). It is
not only unnecessary, but actually dangerous to release the write lock
just in order to take it again in nfs_page_async_flush(). Better just
to open code the pgio operations in a pnfs helper.

As mandated by the standard. In case of an IO error, a pNFS
objects layout driver must return it's layout. This is because
all device errors are reported to the server as part of the
layout return buffer.
This is implemented the same way PNFS_LAYOUTRET_ON_SETATTR
is done, through a bit flag on the pnfs_layoutdriver_type->flags
member. The flag is set by the layout driver that wants a
layout_return preformed at pnfs_ld_{write,read}_done in case
of an error.
(Though I have not defined a wrapper like pnfs_ld_layoutret_on_setattr
because this code is never called outside of pnfs.c and pnfs IO
paths)
Without this patch 3.[0-2] Kernels leak memory and have an annoying
WARN_ON after every IO error utilizing the pnfs-obj driver.

Some time along the way pNFS IO errors were switched to
communicate with a special iodata->pnfs_error member instead
of the regular RPC members. But objlayout was not switched
over.
Fix that!
Without this fix any IO error is hanged, because IO is not
switched to MDS and pages are never cleared or read.

vpif_probe()
The function v4l2_device_register() is called too late in vpif_probe().
This meant that vpif_obj.v4l2_dev is accessed before it is initialized
which caused a crash.
This used to work in the past, but video_register_device() is now actually
using the v4l2_dev pointer.
Note that vpif_display.c doesn't have this bug, there v4l2_device_register()
is called at the beginning of vpif_probe.

Use C99-style initializers with symbolic names for each index to avoid
this. This way, other device tables wanting to reuse the USB ids can
use expressions like "&dw2102_table[TEVII_S630]" that do not change as
the entries in the table are reordered.

As our general practice, we use stream off before we close
the video node. So that the drivers its stream off function
would be called before its remove function.
But for the case for ctrl+c, the program would be force closed.
We have no chance to call that vb2 stream off from user space,
but directly call the remove function in soc_camera.
In that common code of soc_camera:
ici->ops->remove(icd);
if (ici->ops->init_videobuf2)
vb2_queue_release(&icd->vb2_vidq);
It would first call the device remove function, then release vb2,
in which stream off function is called. Thus it create different
order for the driver.
This patch change the order to make driver see the same sequence
to make it happy.
