From 00ba16ab2658afe11d4fdcaf16a331292c44bee6 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 22 Mar 2007 21:51:31 +1100 Subject: [PATCH] MSI: Simplify BUG() handling in msi_remove_pci_irq_vectors() part 2 Although it might be nice to do a printk before BUG'ing, it's really not necessary, and it complicates the code. The behaviour has changed slightly, in that before we set a flag if the irq had an action, and continued freeing the other irqs. But as I see it that's all irrelevant because we end up BUG'ing anyway. Signed-off-by: Michael Ellerman Acked-by: Eric W.
