From 314e77b3eec57001eaff82b82920150175b74e09 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 5 Apr 2007 17:19:12 +1000 Subject: MSI: Remove dev->first_msi_irq Now that we keep a list of msi descriptors, we don't need first_msi_irq in the pci dev. If we somehow have zero MSIs configured list_entry() will give us weird oopes or nice memory corruption bugs. So be paranoid. Add BUG_ONs and also a check in pci_msi_check_device() to make sure nvec > 0.
