From 55a7d60f8f10b1c3c5a8e29571c065d61f5dd12f Mon Sep 17 00:00:00 2001 From: Hugo Cornelis Date: Thu, 21 Mar 2024 12:22:22 +0100 Subject: [PATCH] image-host: Fix error value paths and emit error messages to stderr. A recent refactoring in image-host.c messed up the return values of the function that reads the encryptiong keys. This patch fixes this and also makes sure that error output goes to stderr instead of to stdout.
