Since the jbd_debug() is implemented with two separate printk()

the following (see lines marked with "*"):

[ 290.339365] (fs/jbd2/journal.c, 155): kjournald2: commit_sequence=42103, commit_request=42104

i.e. the debug output from log_wait_commit and journal_commit_transaction
have become interleaved. The output should have been:
(fs/jbd2/journal.c, 648): jbd2_log_wait_commit: JBD2: want 42104, j_commit_sequence=42103

What is interesting here, is that we call log_wait_commit, from
within wait_for_space, but we are still holding the checkpoint_mutex
as it surrounds mostly the whole of wait_for_space. And then, as we
are waiting, journal_commit_transaction can run, and if the JBD2_FLUSHED
bit is set, then we will also try to take the same checkpoint_mutex.
It seems that we need to drop the checkpoint_mutex while sitting in
jbd2_log_wait_commit, if we want to guarantee that progress can be made
by jbd2_journal_commit_transaction(). There does not seem to be
anything preempt-rt specific about this, other then perhaps increasing
the odds of it happening.

This patch changes the driver to avoid the usage of IS_ERR_OR_NULL()
macro. This macro can lead to dangerous results, like returning
success (0) during a failure scenario (NULL pointer handling).
For this reason this patch is changing the driver after
revisiting the code. These are the cases:
i. For cases in which IS_ERR_OR_NULL() is used for checking
return values of functions that returns either PTR_ERR()
or a valid pointer, it has been translated to IS_ERR() check only.
ii. For cases that a NULL check is still needed, it has been
translated to if (!ptr || IS_ERR(ptr)).

This patch corrects the link_notify handler to support more complex
pipelines, including fimc-lite and fimc-is entities.
After the FIMC-IS driver addition the assumptions made in the link_notify
callback are no longer valid, e.g. the link between fimc-lite subdev and
its video node is not immutable any more and there is more subdevs than
just sensor, MIPI-CSIS and FIMC(-LITE).
The graph is now walked and for each video node found a media pipeline
which ends at this node is disabled/enabled (the subdevs are powered
on/off).

Currently the media device link_notify callback is invoked before the
actual change of state of a link when the link is being enabled, and
after the actual change of state when the link is being disabled.
This doesn't allow a media device driver to perform any operations
on a full graph before a link is disabled, as well as performing
any tasks on a modified graph right after a link's state is changed.
This patch modifies signature of the link_notify callback. This
callback is now called always before and after a link's state change.
To distinguish the notifications a 'notification' argument is added
to the link_notify callback: MEDIA_DEV_NOTIFY_PRE_LINK_CH indicates
notification before link's state change and
MEDIA_DEV_NOTIFY_POST_LINK_CH corresponds to a notification after
link flags change.

This patch moves the code for inheriting subdev v4l2 controls on the
FIMC video capture nodes from open()/close() fops to the link setup
notification callback. This allows for the state of the FIMC controls
to be always kept, in opposite to the current situation when it is
lost when last process closes video device.
There is no visible change for the original V4L2 compliant interface.
For the MC aware applications (user_subdev_api == true) inheriting
of the controls is dropped, since there can be same controls on the
subdevs withing single pipeline, now when the ISP (FIMC-IS) is also
used.
This patch is a prerequisite to allow /dev/video device to be opened
without errors even if there is no media links connecting it to an
image source (sensor) subdev. This is required for a libv4l2 plugin
to be initialized while a video node is opened and it also should be
possible to always open the device to query the capabilities.
