The crossbar cleanup frees the media\nentity pads, but the subsequent v4l2 cleanup still tries to remove\nmedia links that reference those pads.\n\nFix this by calling mxc_isi_v4l2_cleanup() before\nmxc_isi_crossbar_cleanup() to ensure all media entities are properly\nunregistered while the pads are still valid.",
