From 4aa9bc955d61fdf03b5f9cee67db188fe1ffa8b7 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 5 Apr 2007 17:19:10 +1000 Subject: MSI: Use a list instead of the custom link structure The msi descriptors are linked together with what looks a lot like a linked list, but isn't a struct list_head list. Make it one. The only complication is that previously we walked a list of irqs, and got the descriptor for each with get_irq_msi(). Now we have a list of descriptors and need to get the irq out of it, so it needs to be in the actual struct msi_desc. We use 0 to indicate no irq is setup.
