linux-4.5-rc5/arch/arm/mach-omap2/omap-mpuss-lowpower.c:297: pointless assignment ?

Hello there,

[linux-4.5-rc5/arch/arm/mach-omap2/omap-mpuss-lowpower.c:297]: (style) Variable 'wakeup_cpu' is assigned a value that is never used.

$ fgrep wakeup_cpu linux-4.5-rc5/arch/arm/mach-omap2/omap-mpuss-lowpower.c
??? unsigned int wakeup_cpu;
??? wakeup_cpu = smp_processor_id();
$

Suggest either assign the variable to something or remove it.
Since there is a function call involved, option 1 looks more likely to me.

Regards
