From 0eeb351222adbc5b534c86f7815ee787babc3485 Mon Sep 17 00:00:00 2001
From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
Date: Tue, 3 Oct 2023 14:34:43 +0300
Subject: [PATCH] media: rp1: fe: Use standard link_validate
The current pisp_fe_link_validate() skips some important checks. Let's
rather use the standard v4l2_subdev_link_validate_default() as the
link_validate hook.
