From ffa437377a6121234cd85d3bd2a8d8c43f0bedd5 Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Mon, 11 Dec 2017 09:18:32 +0000 Subject: [PATCH] ARM: Activate FIQs to avoid __irq_startup warnings There is a new test in __irq_startup that the IRQ is activated, which hasn't been the case for FIQs since they bypass some of the usual setup. Augment enable_fiq to include a call to irq_activate to avoid the warning.
