From d86e9af6336c0ad586a5dbd70064253d40bbb5ff Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Fri, 7 Feb 2014 00:41:58 +0100 Subject: [PATCH] irqchip: orion: Fix getting generic chip pointer. Enabling SPARSE_IRQ shows up a bug in the irq-orion bridge interrupt handler. The bridge interrupt is implemented using a single generic chip. Thus the parameter passed to irq_get_domain_generic_chip() should always be zero.
