[PATCH v2 02/19] powerpc/powermac: Mark variable x as unused

From: Mathieu Malaterre
Date: Wed Mar 28 2018 - 15:30:42 EST


Since the value of x is never intended to be read, remove it. Fix warning
treated as error with W=1:

arch/powerpc/platforms/powermac/udbg_scc.c:76:9: error: variable âxâ set but not used [-Werror=unused-but-set-variable]
