[Qemu-devel] [PATCH] pci: Convert pci_nic_init() to Error to avoid qdev_init()

[Markus Armbruster <armbru@redhat.com>]

qdev_init() is deprecated, and will be removed when its callers have
been weaned off it.

Signed-off-by: Markus Armbruster <armbru@redhat.com>

Depends on my "[PATCH 00/10] pci: Partial conversion to realize",
which is in Michael's latest pull request, and on my "[PATCH v2 2/2]
pci: Give a few helpers internal linkage".
