List-id: Xen developer discussion <xen-devel.lists.xenproject.org>

From: Paul Durrant <pdurrant@xxxxxxxxxx> The seemingly arbitrary use of 'pci' and 'pcidev' in the code in libxl_pci.c is confusing and also compromises use of some macros used for other device types. Indeed it seems that DEFINE_DEVICE_TYPE_STRUCT_X exists solely because of this duality. This patch purges use of 'pcidev' from the libxl code, allowing evaluation of DEFINE_DEVICE_TYPE_STRUCT_X to be replaced with DEFINE_DEVICE_TYPE_STRUCT, hence allowing removal of the former. For consistency the xl and libs/util code is also modified, but in this case it is purely cosmetic. NOTE: Some of the more gross formatting errors (such as lack of spaces after keywords) that came into context have been fixed in libxl_pci.c.
