Hi!

On 1/17/23 18:01, Geert Uytterhoeven wrote:

The issue is that some of the parameters are not arrays, but
NULL. E.g.:

arch/sh/kernel/cpu/sh2/setup-sh7619.c:static
DECLARE_INTC_DESC(intc_desc, "sh7619", vectors, NULL,
arch/sh/kernel/cpu/sh2/setup-sh7619.c-                   NULL,
prio_registers, NULL);


Isn't this supposed to be caught by this check:

	a, __same_type(a, NULL)

?
