Subject: media: atomisp: Add target validation to atomisp_subdev_set_selection() Author: Hans de Goede <[email protected]> Date: Mon May 29 11:37:30 2023 +0100 As the 2 comments in the function already say both the sink and the source pads only support setting the selection for 1 target: /* Only crop target supported on sink pad. */ /* Only compose target is supported on source pads. */ Validate that the passed in target actually matches these expectations.
