Memory allocated by alloc_page() function might contain some potentially
important data from other system processes. The patch adds a flag to
zero the allocated page before giving it to videobuf2 (and then to
userspace).

This patch fixes 2 minor bugs in videobuf2 core:
1. Queue should be reallocated if one change the memory access
method without changing the number of buffers.
2. In case of REQBUFS(0), the request should not be passed to the

Use pr_debug instead of printk so it is possible to control
debug traces at runtime.
E.g. to enable debug trace in file fimc-core.c use command:
echo -n 'file fimc-core.c +p' > /sys/kernel/debug/dynamic_debug/control
or
echo -n 'file fimc-core.c -p' > /sys/kernel/debug/dynamic_debug/control
to disable.

Rework the locking in m2m driver to assure proper operation on SMP systems.
When job_abort or stop_streaming was called to immediately shutdown
a memory-to-memory transaction video buffers scheduled for processing
were never returned to vb2 and v4l2_m2m_job_finish was not called
which led to hanging.
Correct this and also return the unprocessed buffers to vb2 marking
them as erroneous, in case the end of frame interrupt do not occur.

In some cases fimc H/W did not stop although there were no output
buffers available. So the capture deactivation interrupt routine
is modified and the state of ST_CAPT_RUN is cleared only
in the LAST-IRQ call.
After LAST-IRQ is generated, H/W pointer will be skipped by 1 frame.
(reference by user manual) So, S/W pointer should be increased too.

Add a userspace API to get, set and enumerate the media format on a
subdev pad.
The format at the output of a subdev usually depends on the format at
its input(s). The try format operation is thus not suitable for probing
format at individual pads, as it can't modify the device state and thus
can't remember the format tried at the input to compute the output
format.
To fix the problem, pass an extra argument to the get/set format
operations to select the 'try' or 'active' format.
The try format is used when probing the subdev. Setting the try format
must not change the device configuration but can store data for later
reuse. Data storage is provided at the file-handle level so applications
probing the subdev concurently won't interfere with each other.
The active format is used when configuring the subdev. It's identical to
the format handled by the usual get/set operations.

V4L2 subdevices are media entities. As such they need to inherit from
(include) the media_entity structure.
When registering/unregistering the subdevice, the media entity is
automatically registered/unregistered. The entity is acquired on device
open and released on device close.

V4L2 devices are media entities. As such they need to inherit from
(include) the media_entity structure.
When registering/unregistering the device, the media entity is
automatically registered/unregistered. The entity is acquired on device
open and released on device close.
