Subject: [PATCH 5.12 222/384] media: uvcvideo: Fix XU id print in forward scan

From: Laurent Pinchart <laurent.pinchart@...asonboard.com>

[ Upstream commit 3293448632ff2ae8c7cde4c3475da96138e24ca7 ]

An error message in the forward scan code incorrectly prints the ID of
the source entity instead of the XU entity being scanned. Fix it.
