Subject: sparseirq, powerpc/cell: fix unused variable warning in interrupt.c
X-Git-Tag: v2.6.30-rc1~3^2~8
X-Git-Url: http://bbs.cooldavid.org/git/?a=commitdiff_plain;h=a6bc3262c561780d2a6587aa3d5715b1e7d8fa13;p=net-next-2.6.git

sparseirq, powerpc/cell: fix unused variable warning in interrupt.c

This new compiler warning:

   arch/powerpc/platforms/cell/interrupt.c: In function 'handle_iic_irq':
   arch/powerpc/platforms/cell/interrupt.c:240: warning: unused variable 'cpu'

Triggers because the local variable 'cpu' became unused due to commit:

   dee4102: sparseirq: use kstat_irqs_cpu instead

Remove the variable.
