Since the value of x is never intended to be read, declare it with gcc
attribute as unused. Fix warning treated as error with W=1:
arch/powerpc/platforms/powermac/bootx_init.c:471:21: error: variable ‘x’ set
but not used [-Werror=unused-but-set-variable]
Suggested-by: Christophe Leroy <christophe.le...@c-s.fr>
Signed-off-by: Mathieu Malaterre <ma...@debian.org>
---
v3: style: add missing empty line after declaration
v2: move x variable within its local scope
