From 58febc0b1374de7506277d3aa9e9cddaea62ba65 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Tue, 23 Jan 2007 20:21:36 -0800 Subject: [PATCH] [AVR32] ext int fixes Bugfixes for external irq handler set_irq_type(): - If set_irq_type() can't set the type, don't change anything! - It's not OK to change the flow handler as part of set_irq_type(), among other issues that violates spinlock rules. Instead, we can call the relevant handler when we demux the external interrupts. - The external irq demux has no need to grab the spinlock. And in fact grabbing it that way was wrong, since that code might be pre-empted by an irq at a different priority level, and that code might then have tried to grab that spinlock...
