From 25a98bd4ff9355a218d2e7aa4d6e3c9bc2c27d6f Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Thu, 9 Jul 2015 16:00:45 +0800 Subject: genirq/MSI: Store 'struct device' instead of 'struct pci_dev' in struct msi_desc Store 'struct device *' instead of 'struct pci_dev *' in struct msi_desc, so struct msi_desc can be reused by non PCI based MSI drivers.
