vsp-lib: Reset controls to defaults on each test run
Some of our tests set flipping and rotation controls, and the VSP instance can be used again by later tests. If these controls are not reset, then that operation is applied to later tests incorrectly causing those tests to fail. In an ideal world, tests should clean up after themselves, and leave the system in a known state. However the world is not ideal and we would not be able to guarantee any previous system state before a test was run anyway. Therefore it is more effective to reset state at the beginning of a test. To repair this - reset all control values to their defaults at the start of every test during test_init() Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
