From 090afdc5e61e80de4ac158fa4cb2a578ee69be54 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Mon, 2 Nov 2020 13:19:53 -0500 Subject: [PATCH] cutils: replace strdup with g_strdup Memory returned by get_relocated_path must be freed with free or g_free depending on the path that the function took; Coverity takes exception to this practice. The fix lets caller use g_free as is standard in QEMU. While at it, mention the requirements on the caller in the doc comment.
