[PATCH] arm64/smp: Drop unsued local variable 'irq'
From: Anshuman Khandual <hidden>

Subsystem:
arm64 port (aarch64 architecture), the rest · Maintainers:
Catalin Marinas, Will Deacon, Linus Torvalds
Previous commit 5089bc51f81f05ad ("arm64/smp: Use irq_desc_kstat_cpu() in
arch_show_interrupts()") started using irq_desc_kstat_cpu() that does not
require local variable 'irq' anymore. Hence just drop it. Saves the cost
for irq_desc_get_irq() as well.
