I am not able to reproduce these warnings with clang 19.1.7. They also
don't obviously make sense to me.

Please, when reply, remove boielrplate stuff!
I have just wasted a couple of minutes to understand what's going on in the
message that is 2700 lines of text as the reply to the bot message which was
~700 lines.

My apologies. I forgot what a mess a mobile email client makes.

I have reproduced the problem with gcc:
$> gcc --version
gcc (SUSE Linux) 14.2.1 20250220 [revision 9ffecde121af883b60bbe60d00425036bc873048]
$> make W=1 lib/test_scanf.ko
CALL scripts/checksyscalls.sh
DESCEND objtool
INSTALL libsubcmd_headers
CC [M] lib/test_scanf.o
In file included from <command-line>:
lib/test_scanf.c: In function ‘numbers_list_ll’:
./include/linux/compiler.h:197:61: warning: function ‘numbers_list_ll’ might be a candidate for ‘gnu_scanf’ format attribute [-Wsuggest-attribute=format]
197 | #define __BUILD_BUG_ON_ZERO_MSG(e, msg) ((int)sizeof(struct {_Static_assert(!(e), msg);}))
| ^
[...]
It seems that it is a regression introduced by the first
patch of this patch set. And the fix is:
diff --git a/lib/test_scanf.c b/lib/test_scanf.c
index d1664e0d0138..e65b10c3dc11 100644
--- a/lib/test_scanf.c
