This is version 2 of the patch series posted by Niklas for allowing
multiple streams in VIMC.
The original series can be found here:
https://patchwork.kernel.org/cover/10948831/

This series adds support for two (or more) capture devices to be 
connected to the same sensors and run simultaneously. Each capture device 
can be started and stopped independent of each other.

Patch 1/3 and 2/3 deals with solving the issues that arises once two 
capture devices can be part of the same pipeline. While 3/3 allows for 
two capture devices to be part of the same pipeline and thus allows for 
simultaneously use.

Changes since v1:
	- All three patches rebased on latest media-tree.
	Patch 3:
	- Search for an entity with a non-NULL pipe instead of searching
	  for sensor. This terminates the search at output itself.

Kaaira Gupta (3):
  media: vimc: Add usage count to subdevices
  media: vimc: Serialize vimc_streamer_s_stream()
  media: vimc: Join pipeline if one already exists
