From 76c78a548144b69ecc3ed9cc2d670297983da6b1 Mon Sep 17 00:00:00 2001 From: Alexandru Gagniuc Date: Mon, 11 Jan 2021 08:46:58 -0600 Subject: [PATCH] common: fit-sig: Fix error message in fit_config_verify_sig() In fit_config_verify_sig(), when no 'signature*' subnode exists in the configuration node, the fdt_for_each_subnode() loop is a no-op. Therefore, no error flags are set, and 'err_,sg' is not populated with an error string. This is incorrect behavior. Populate err_msg to indicate that no 'signature' is found, before entering the loop. The first call to fit_image_verify_sig() will override clear err_msg, or set it to a more specific message.
