Make sure format is a string and not a pointer. This prevents usages like: spice_debug(NULL); This forbids computed format strings, but on the other hand, forcing the use of string constants allows the compiler to always check argument types against the format string. Moreover, there is no occurrences of computed format strings in the current codebase. Signed-off-by: Frediano Ziglio <fziglio@redhat.com> Acked-by: Christophe Fergeau <cfergeau@redhat.com>
