ia64: agp: Replace empty define with do while
It's dangerous to use empty code define. Furthermore it lead to the following warning: drivers/char/agp/generic.c: In function « agp_generic_destroy_page »: drivers/char/agp/generic.c:1266:28: attention : suggest braces around empty body in an « if » statement [-Wempty-body] So let's replace emptyness by "do {} while(0)" Signed-off-by: Corentin Labbe <clabbe@baylibre.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Dave Airlie <airlied@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/1574324085-4338-6-git-send-email-clabbe@baylibre.com
