From fa6beb37b0d9bc00f90f11154eeed9502d8b0a37 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Mon, 22 Dec 2008 20:24:09 -0800 Subject: sparseirq: set lock_class for legacy irq when sparse_irq is selected Impact: add lockdep annotation to legacy IRQ descs Warnings resulting out of this were not seen in practice, but it's prudent to initialize the legacy descriptors to the lock class as well, symmetric to how we do it with other descriptors.
