From d2bbf3da3759d04cd5836955cc59c8ae96092831 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Thu, 4 Oct 2007 08:52:40 +0200 Subject: Sysace: Don't enable IRQ until after interrupt handler is registered The previous patch to move the interrupt handler registration moved it below enabling interrupts which could be a problem if the device is on a shared interrupt line. This patch fixes the order.
