If a driver calls (_)vb2_fop_release(), then such a driver should also
call vb2_video_unregister_device() instead of video_unregister_device().
This helper will call vb2_queue_release() if a filehandle is marked as
owner of the queue. This ensures that at unregister time any streaming
is cancelled and all buffers are returned to userspace.
This is very useful for complex drivers since this stops all streaming
in all subdevs in the pipeline controlled by this video device. Otherwise
this would be delayed until the owner filehandle is closed, which can be
quite some time later.

pm_runtime_get_sync() increments the runtime PM usage counter even
when it returns an error code. Thus a pairing decrement is needed on
the error handling path to keep the counter balanced. For other error
paths after this call, things are the same.
Fix this by adding pm_runtime_put_noidle() after 'err_runtime_disable'
label. But in this case, the error path after pm_runtime_put_sync()
will decrease PM usage counter twice. Thus add an extra
pm_runtime_get_noresume() in this path to balance PM counter.

Move the PXA camera driver to use the new set_mbus_config pad operation.
For this platform the change is not only cosmetic, as the pxa driver is
currently the only driver in mainline to make use of the g_mbus_config
and s_mbus_config video operations.
The existing driver semantic is the following:
- Collect all supported mbus config flags from the remote end
- Match them with the supported PXA mbus configuration flags
- If the remote subdevice allows multiple options for for VSYNC, HSYNC
and PCLK polarity, use platform data requested settings
The semantic of the new get_mbus_config and set_mbus_config differs from
the corresponding video ops, particularly in the fact get_mbus_config
reports the current mbus configuration and not the set of supported
configuration options, with set_mbus_config always reporting the actual
mbus configuration applied to the remote subdevice.
Adapt the driver to perform the following
- Set the remote subdevice mbus configuration according to the PXA
platform data preferences.
- If the applied configuration differs from the requested one (i.e. the
remote subdevice does not allow changing one setting) make sure that
- The remote end does not claim for DATA_ACTIVE_LOW, which seems not
supported by the platform
- The bus mastering roles match
While at there remove a few checks performed on the media bus
configuration at get_format() time as they do not belong there.
Compile-tested only.

of the video operations currently in use.
Compared to other drivers where the same conversion has been performed,
ov6650 proved to be a bit more tricky, as the existing g_mbus_config
implementation did not report the currently applied configuration but
the set of all possible configuration options.
Adapt the driver to support the semantic of the two newly introduced
operations:
- get_mbus_config reports the current media bus configuration
- set_mbus_config applies only changes explicitly requested and updates
the provided cfg parameter to report what has actually been applied to
the hardware.

static priority level knowledge from non-scheduler code.
The three APIs for non-scheduler code to set SCHED_FIFO are:
- sched_set_fifo()
- sched_set_fifo_low()
- sched_set_normal()
These are two FIFO priority levels: default (high), and a 'low' priority level,
plus sched_set_normal() to set the policy back to non-SCHED_FIFO.
Since the changes affect a lot of non-scheduler code, we kept this in a separate
tree.
When merging to the latest upstream tree there's a conflict in drivers/spi/spi.c,
which can be resolved via:
sched_set_fifo(ctlr->kworker_task);

camss_probe() does not free camss on error handling paths. The patch
introduces an additional error label for this purpose. Besides, it
removes call of v4l2_async_notifier_cleanup() from
camss_of_parse_ports() since its caller, camss_probe(), cleans up all
its resources itself.

In case of errors vpif_probe_complete() releases memory for vpif_obj.sd
and unregisters the V4L2 device. But then this is done again by
vpif_probe() itself. The patch removes the cleaning from
vpif_probe_complete().

The variable retval is being initialized with a value that is
never read and it is being updated later with a new value. The
initialization is redundant and can be removed.

Drivers using legacy PM have to manage PCI states and device's PM states
themselves. They also need to take care of configuration registers.
With improved and powerful support of generic PM, PCI Core takes care of
above mentioned, device-independent, jobs.
This driver makes use of PCI helper functions like
pci_save/restore_state() and pci_enable/disable_device() to do required
operations. In generic mode, they are no longer needed.
Change function parameter in both .suspend() and .resume() to
"struct device*" type.
Compile-tested only.
