From d6c49a7a78fc841418bbd58bda504076f80ec51d Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen Date: Thu, 24 Jan 2008 16:56:53 +0100 Subject: [AVR32] extint: Set initial irq type to low level David Brownell pointed out a mismatch in the avr32 extint code: > I noticed a small glitch that's not fixed by this patch: the > initial type is falling edge, but IRQ_TYPE_NONE is mapped to > IRQ_TYPE_LEVEL_LOW. Potentially surprising. Fix it by setting the initial type (and handler) to low level, matching the meaning of IRQ_TYPE_NONE.
