[PATCH] irq: generic-chip: pass an irq in chip to suspend/resume

From: Colin Cross
Date: Fri Mar 16 2012 - 19:10:08 EST


irq_gc_suspend and irq_gc_resume pass the irq_data of irq_base
to the ops, but if irq_mask bit 0 is not set, that irq_data is
not part of the generic chip, and there is no way to get to the
generic chip data from there. Instead, pass the irq_data of
gc->irq_base + gc->irq_cnt - 1, which is guaranteed to be part
of this generic chip.
