Pull new experimental media request API from Mauro Carvalho Chehab:
 "A new media request API

  This API is needed to support device drivers that can dynamically
  change their parameters for each new frame. The latest versions of
  Google camera and codec HAL depends on such feature.

  At this stage, it supports only stateless codecs.

  It has been discussed for a long time (at least over the last 3-4
  years), and we finally reached to something that seem to work.

  This series contain both the API and core changes required to support
  it and a new m2m decoder driver (cedrus).

  As the current API is still experimental, the only real driver using
  it (cedrus) was added at staging[1]. We intend to keep it there for a
  while, in order to test the API. Only when we're sure that this API
  works for other cases (like encoders), we'll move this driver out of
  staging and set the API into a stone.

  [1] We added support for the vivid virtual driver (used only for
  testing) to it too, as it makes easier to test the API for the ones
  that don't have the cedrus hardware"

Mauro Carvalho Chehab 3b796aa60a media: rename soc_camera I2C drivers
Those drivers are part of the legacy SoC camera framework.
They're being converted to not use it, but sometimes we're
keeping both legacy any new driver.

This time, for example, we have two drivers on media with
the same name: ov772x. That's bad.

So, in order to prevent that to happen, let's prepend the SoC
legacy drivers with soc_.

No functional changes.

Hans Verkuil 490d84f6d7 media: cec: forgot to cancel delayed work
If the wait for completion was interrupted, then make sure to cancel
any delayed work.

This can only happen if a transmit is waiting for a reply, and you press
Ctrl-C or reboot/poweroff or something like that which interrupts the
thread waiting for the reply and then proceeds to delete the CEC message.

Since the delayed work wasn't canceled, once it would trigger it referred
to stale data and resulted in a kernel oops.

The cause turned out to be a division of a negative number by an unsigned value.

Colin Ian King 32ae592036 media: cx231xx: fix potential sign-extension overflow on large shift
Shifting the u8 value[3] by an int can lead to sign-extension
overflow. For example, if value[3] is 0xff and the shift is 24 then it
is promoted to int and then the top bit is sign-extended so that all
upper 32 bits are set.  Fix this by casting value[3] to a u32 before
the shift.

Wenwen Wang a26ac6c1be media: isif: fix a NULL pointer dereference bug
In isif_probe(), there is a while loop to get the ISIF base address and
linearization table0 and table1 address. In the loop body, the function
platform_get_resource() is called to get the resource. If
platform_get_resource() returns NULL, the loop is terminated and the
execution goes to 'fail_nobase_res'. Suppose the loop is terminated at the
first iteration because platform_get_resource() returns NULL and the
execution goes to 'fail_nobase_res'. Given that there is another while loop
at 'fail_nobase_res' and i equals to 0, one iteration of the second while
loop will be executed. However, the second while loop does not check the
return value of platform_get_resource(). This can cause a NULL pointer
dereference bug if the return value is a NULL pointer.

This patch avoids the above issue by adding a check in the second while
loop after the call to platform_get_resource().

Hans Verkuil c439d5c1e1 media: cec-gpio: select correct Signal Free Time
If a receive is in progress or starts before the transmit has
a chance, then lower the Signal Free Time of the upcoming transmit
to no more than CEC_SIGNAL_FREE_TIME_NEW_INITIATOR.

This is per the specification requirements.

Hans Verkuil 7d867a1b76 media: cec: fix the Signal Free Time calculation
The calculation of the Signal Free Time in the framework was not
correct. If a message was received, then the next transmit should be
considered a New Initiator and use a shorter SFT value.

This was not done with the result that if both sides where continually
sending messages, they both could use the same SFT value and one side
could deny the other side access to the bus.

Note that this fix does not take the corner case into account where
a receive is in progress when you call adap_transmit.

Hans Verkuil 7ec2b3b941 media: cec: add new tx/rx status bits to detect aborts/timeouts
If the HDMI cable is disconnected or the CEC adapter is manually
unconfigured, then all pending transmits and wait-for-replies are
aborted. Signal this with new status bits (CEC_RX/TX_STATUS_ABORTED).

If due to (usually) a driver bug a transmit never ends (i.e. the
transmit_done was never called by the driver), then when this times
out the message is marked with CEC_TX_STATUS_TIMEOUT.

This should not happen and is an indication of a driver bug.

Without a separate status bit for this it was impossible to detect
this from userspace.

The 'transmit timed out' kernel message is now a warning, so this
should be more prominent in the kernel log as well.

As pointed at:
	https://bugzilla.kernel.org/show_bug.cgi?id=199323

This patch causes a bad effect on RPi. I suspect that the root
cause is at the USB out of tree RPi driver, with uses high priority
interrupts instead of normal ones. Anyway, as this patch
is mostly a cleanup, better to revert it.

This reverts commit 7d95fb746c.

   exposure = ((reg2 & 0x3f) << 10) | (reg1 << 2) |
              ~~~~~~~~~~~~~~~^~~~~~

It is apparently hard for the compiler to see here if ov965x_read()
returned successfully or not. Besides, we have a v4l2_dbg() statement
that prints an uninitialized value if regmap_read() fails.

Adding an 'else' clause avoids the ambiguity.
