[PATCH 3/4] powerpc: Use IRQF_NO_SUSPEND not IRQF_TIMER for non-timer interrupts

From: Ian Campbell
Date: Wed Jul 28 2010 - 06:54:46 EST


kw_i2c_irq and via_pmu_interrupt are not timer interrupts and
therefore should not use IRQF_TIMER. Use the recently introduced
IRQF_NO_SUSPEND instead since that is the actual desired behaviour.
