Subject: [PATCH] media: rzg2l-csi2: Use common error handling code in
 rzg2l_csi2_parse_dt()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 1 Mar 2024 14:02:22 +0100

Add a label so that a bit of exception handling can be better reused
in an if branch of this function implementation.
