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. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>
