config_odev* functions are called in code-paths were we already use XNF* functions in other places, so which are not oom safe already. Besides that oom is something which should simply never happen, so aborting when it does is as good a response as any other. While switching to XNF functions also fixup an unchecked strdup case. Note the function prototypes are kept unchanged, as they are part of the server ABI. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Peter Hutterer <peter.hutterer@who-t.net>
