The wakeup_cpu variable in omap4_enter_lowpower() is set
but then is not used after this. Remove it to fix
the compiler warning:
arch/arm/mach-omap2/omap-mpuss-lowpower.c: In function âomap4_enter_lowpowerâ:
arch/arm/mach-omap2/omap-mpuss-lowpower.c:230:15: warning: variable âwakeup_cpuâ set but not used [-Wunused-but-set-variable]
