From 5250b09e57d9989efc69353d18416aedde00995e Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 14 Dec 2018 13:30:51 +0000 Subject: [PATCH] hw/i386/multiboot.c: Don't use load_image() The load_image() function is deprecated, as it does not let the caller specify how large the buffer to read the file into is. Instead use load_image_size(). While we are converting the code, add the missing error check.
