713bdfa10b media: cec-pin: fix interrupt en/disable handling
The en/disable_irq() functions keep track of the 'depth': i.e. if
interrupts are disabled twice, then it needs to enable_irq() calls to
enable them again. The cec-pin framework didn't take this into accound
and could disable irqs multiple times, and it expected that a single
enable_irq() would enable them again.

Move all calls to en/disable_irq() to the kthread where it is easy
to keep track of the current irq state and ensure that multiple
en/disable_irq calls never happen.

If interrupts where disabled twice, then they would never turn on
again, leaving the CEC adapter in a dead state.

cf56f4f2a4 media: s5p-jpeg: Constify struct v4l2_m2m_ops
The only usage of the v4l2_m2m_ops structs is to pass their address to
v4l2_m2m_init() which takes a pointer to const struct v4l2_m2m_ops as
argument. Make them const to allow the compiler to put them in read-only
memory.

0407c49ebe media: saa7146: mxb: Fix a NULL pointer dereference in mxb_attach()
In mxb_attach(dev, info), saa7146_vv_init() is called to allocate a
new memory for dev->vv_data. saa7146_vv_release() will be called on
failure of mxb_probe(dev). There is a dereference of dev->vv_data
in saa7146_vv_release(), which could lead to a NULL pointer dereference
on failure of saa7146_vv_init().

Fix this bug by adding a check of saa7146_vv_init().

This bug was found by a static analyzer. The analysis employs
differential checking to identify inconsistent security operations
(e.g., checks or kfrees) between two code paths and confirms that the
inconsistent operations are not recovered in the current function or
the callers, so they constitute bugs.

Note that, as a bug found by static analysis, it can be a false
positive or hard to trigger. Multiple researchers have cross-reviewed
the bug.

Builds with CONFIG_VIDEO_MXB=m show no new warnings,
and our static analyzer no longer warns about this code.

348df80353 media: saa7146: hexium_orion: Fix a NULL pointer dereference in hexium_attach()
In hexium_attach(dev, info), saa7146_vv_init() is called to allocate
a new memory for dev->vv_data. In hexium_detach(), saa7146_vv_release()
will be called and there is a dereference of dev->vv_data in
saa7146_vv_release(), which could lead to a NULL pointer dereference
on failure of saa7146_vv_init() according to the following logic.

Both hexium_attach() and hexium_detach() are callback functions of
the variable 'extension', so there exists a possible call chain directly
from hexium_attach() to hexium_detach():

hexium_attach(dev, info) -- fail to alloc memory to dev->vv_data
	|		    		in saa7146_vv_init().
	|
	|

468613a67b media: rcar-vin: Do not hold the group lock when unregistering notifier
There is no need to hold the group lock when unregistering the notifier,
but doing so triggers a warning about a possible cyclic lock dependency.

The lock warning cover the case where a subdevice is about to be bound
to the notifier at the same time as it's unregistered. The locking for
this scenario is handled in the v4l2-async framework so it's safe to
remove the lock in the driver. This match the locking logic in the
driver for when the notifier in question is registered.

e37e82188b media: rcar-vin: Disallow unbinding and binding of individual VINs
The VIN driver have an internal concept of capture groups that covers
multiple instances of the driver. This is handled using the shared media
graph and a single notifier shared between all VIN instances.

This design do not work well if an individual VIN where to be unbound on
its own. The design could be improved up on to allow for this but would
require large changes in the v4l2-async framework. To avoid the
situation suppress the bind and unbind nodes in sysfs.

0d7b74ef8d media: rcar-csi2: Suppress bind and unbind nodes in sysfs
The v4l2-async framework's subdev notifiers do not behave correctly if a
device in the middle of the pipeline is unbound and then rebound. The
v4l2-subdevices upstream from the device being rebound gets confused as
they receive no notification of the device unbound and can't cleanup
their state and when they are rebound to the new v4l2-subdev notifier
they try to reinitialize their internal state, this may include things
as trying to create links that already exists and in some cases crash
the system, for example the adv748x.

This should be solved in the v4l2-async framework, but as a stop-gap
measure suppress the bind and unbind sysfs nodes for the rcar-csi2
driver so it can't be used to crash the system.

da6911f330 media: rcar-vin: Update format alignment constraints
This change fixes two issues with the size constraints for buffers.

- There is no width alignment constraint for RGB formats. Prior to this
  change they were treated as YUV and as a result were more restricted
  than needed. Add a new check to differentiate between the two.

- The minimum width and height supported is 5x2, not 2x4, this is an
  artifact from the driver's soc-camera days. Fix this incorrect
  assumption.
