Subject[PATCH v2 01/19] powerpc/powermac: Mark variable x as unused
Date
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]

Signed-off-by: Mathieu Malaterre <malat@debian.org>

v2: move x variable within its local scope
