Hello, This small patch series addresses an incorrect (in my opinion) warning printed by the v4l2_subdev_link_validate() helper. Patch 1/2 is a small drive-by cleanup, and the important change is in 2/2. Please see the patch commit message for details. The series has been tested with the VSP1 driver, and correctly gets rid of the warning.
