From: Arnd Bergmann <[email protected]> Building with 'make W=1' shows a warning for an empty macro:
security/apparmor/label.c: In function '__label_update': security/apparmor/label.c:2096:59: error: suggest braces around empty body in an 'else' statement [-Werror=empty-body] 2096 | AA_BUG(labels_ns(label) != labels_ns(new)); Change the macro defintion to use no_printk(), which improves format string checking and avoids the warning.
