From 5093aec872e5be7a55d8dd2b639e8a3818dc19db Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Thu, 24 Mar 2011 12:47:04 +0100 Subject: [PATCH] arm: davinci: Cleanup irq chip code Make use of the new functionality which ensures that irq_set_type is called with the chip masked. Unmask is only done when the interrupt is not disabled.
