From e75ec752d725b7b612c0b2db1bca50a9e53c0879 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 22 May 2015 11:12:39 +0200 Subject: [PATCH] nvme: store a struct device pointer in struct nvme_dev Most users want the generic device, so store that in struct nvme_dev instead of the pci_dev. This also happens to be a nice step towards making some code reusable for non-PCI transports.
