[PATCH] pinctrl: th1520: Use common error handling code in th1520_pinctrl_dt_node_to_map()

[Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Thu, 10 Oct 2024 08:22:14 +0200

Add jump targets so that a bit of exception handling can be better reused
at the end of this function implementation.
