From 71a7d1556264c1ad84b1bcf5f7a9cbc980b1e1fd Mon Sep 17 00:00:00 2001 From: Sonic Zhang Date: Wed, 25 Jun 2008 12:02:07 +0800 Subject: [PATCH] Blackfin arch: fix bug - kernel boot fails when Spinlock and rw-lock debugging enabled Initialize the lock of bad_irq_desc properly. The content of irq_desc array is replaced by bad_irq_desc in blackfin arch irqchip init code. So, do it properly as common irq init code.
