Subject: [PATCH] arm64/smp: Remove unused 'irq' variable

From: Arnd Bergmann <arnd@...db.de>

The only use of this variable was removed in a recent patch:

arch/arm64/kernel/smp.c:810:16: error: unused variable 'irq' [-Werror,-Wunused-variable]
                unsigned int irq = irq_desc_get_irq(ipi_desc[i]);

Fixes: 5089bc51f81f ("arm64/smp: Use irq_desc_kstat_cpu() in arch_show_interrupts()")
