Subject: reboot: hide unused hw_protection_attr
Date: Mon, 24 Feb 2025 15:16:09 +0100
The reference to hw_protection_attr is inside of an #ifdef block, but the
definition is not:
kernel/reboot.c:1092:30: error: unused variable 'hw_protection_attr' [-Werror,-Wunused-variable]
1092 | static struct kobj_attribute hw_protection_attr = __ATTR_RW(hw_protection);
| ^~~~~~~~~~~~~~~~~~
Add another #ifdef to match the first.
