[PATCH 0/3] VSP-Tests: unbind:

[PATCH 0/3] VSP-Tests: unbind:

[Kieran Bingham]

The VSP unbind test recently added causes an issue when the VSP utilised
by the DU is unbound and rebound.

That needs to be fixed, but will be handled separately - so we limit the
scope to allow running the remaining tests for now.

As the unbind test requires root to run, skip it if it's run by a normal
user, and while were here - remove an unused variable identified during
the creation of these patches.

  scripts: vsp-lib.sh: Remove unused variable
  tests: Skip unbind/bind tests when not root
  tests: unbind/bind: Only test non display VSPs

[PATCH 1/3] scripts: vsp-lib.sh: Remove unused variable

[Kieran Bingham]

The dev identifier is not used until after a media device has been
selected, at which point the vsp1_device function is re-called.

Remove the redundant assignment.

[PATCH 2/3] tests: Skip unbind/bind tests when not root

[Kieran Bingham]

The user must be root to be able to perform the unbind/bind cycle.
Skip this test when the user does not have root privilidges.

Ugh, this is a bit annoying as it generates a warning on the output
actually, as we haven't yet called test_start.

We could do a test_start "Rebinding VSPs", and then it will either skip
or pass. But any failures would be in the kernel logs...

v2:
 - Provide a test_start to match the test_complete operations.

[PATCH 3/3] tests: unbind/bind: Only test non display VSPs

[Kieran Bingham]

Only perform bind/unbind testing on VSPs which expose a media-device.
Unbinding a VSP which is connected to a DU causes the display pipeline
to fail, and is not currently supported.
