From 0766d20fdb9178b908f0268c16b464c11822c5c2 Mon Sep 17 00:00:00 2001 From: Feng Tang Date: Tue, 25 Jan 2011 15:07:15 -0800 Subject: [PATCH] langwell_gpio: modify EOI handling following change of kernel irq subsystem Latest kernel has many changes in IRQ subsystem and its interfaces, like adding "irq_eoi" for struct irq_chip, this patch is a follow up change for that. Also remove the unnecessary cast for a "void *".
