Subject: panic: suppress gnu_printf warning
Date: Sun, 7 Jan 2024 17:16:41 +0800
with GCC 13.2.1 and W=1, there's compiling warning like this:
kernel/panic.c: In function `__warn':
kernel/panic.c:676:17: warning: function `__warn' might be a candidate for `gnu_printf' format attribute [-Wsuggest-attribute=format]
676 | vprintk(args->fmt, args->args);
| ^~~~~~~
The normal __printf(x,y) adding can't fix it. So add workaround which
disables -Wsuggest-attribute=format to mute it.
