From e2449ee9680cd316a70053bb638b76e96c6578e5 Mon Sep 17 00:00:00 2001 From: Yannic Moog Date: Wed, 20 Dec 2023 09:45:36 +0100 Subject: [PATCH] board: phytec: phytec_som_detection: fix uninitialized bug When som_type does not match any case, it is uninitialized and the function still tries to print the SoM info. Rather, this is an error condition and the function should abort prematurely. Highlight this by printing an error message and returning early.
