It is needed since there are different firmwares used across various

[media] media: Change media device link_notify behaviour
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

to be always kept, in opposite to the current situation when it is

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
