android: Return -EUSERS when failed to open a Camera that's in use
The correct return value for the HAL for hal_dev_open() when trying to open a camera that's already opened is EUSERS. Make hal_dev_open() return -EUSERS, and plumb the logic for this through CameraHalManager::open(). This allows the following CTS tests to pass: - android.hardware.camera2.cts.CameraManagerTest#testCameraManagerOpenAllCameras - android.hardware.camera2.cts.MultiViewTest#testDualCameraPreview Signed-off-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Hirokazu Honda <hiroh@chromium.org> Reviewed-by: Jacopo Mondi <jacopo@jmondi.org>
