PCI MSI: msi_desc->dev is always initialised
By passing the pci_dev into alloc_msi_entry() we can be sure that the ->dev entry is always assigned and so we don't need to check it. Also, we used kzalloc() so we don't need to initialise ->irq to 0. Signed-off-by: NMatthew Wilcox <willy@linux.intel.com> Signed-off-by: NJesse Barnes <jbarnes@virtuousgeek.org>
