Date: Fri, 16 Mar 2012 16:10:02 -0700 From: Colin Cross <ccross@...roid.com> To: linux-kernel@...r.kernel.org Cc: Colin Cross <ccross@...roid.com>, Thomas Gleixner <tglx@...utronix.de> Subject: [PATCH] irq: generic-chip: pass an irq in chip to suspend/resume 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.
