Hi, in recent changes of linux-next.patch

==
static void __init param_sysfs_builtin(void)
{
        struct kernel_param *kp;
        unsigned int name_len;
        char modname[MODULE_NAME_LEN];

        for (kp = __start___param; kp < __stop___param; kp++) {
                char *dot;

                if (kp->perm == 0)
                        continue;

                dot = strchr(kp->name, '.');
                BUG_ON(!dot); <======================================(*)
                name_len = dot - kp->name + 1;
                strlcpy(modname, kp->name, name_len);
                kernel_add_sysfs_param(modname, kp, name_len);
        }

Above (*) is added.

I hit BUG_ON() at (*). That was because usbcore was not a module and module param
kp->name was "nousb".... not including any dot.
(If compled as module, the kernel works well.)

I'm sorry if already fixed.

Thanks,
-Kame
