Subject: [PATCH v2, part 1 3/9] PCI: Convert alloc_pci_dev(void) to pci_alloc_dev(bus) instead
From: Gu Zheng <guz.fnst@...fujitsu.com>
<marker to prevent gmail from removing below "From:">
From: Gu Zheng <guz.fnst@...fujitsu.com>
Use the new pci_alloc_dev(bus) to replace the existing using of
alloc_pci_dev(void).
v2:
Follow Bjorn's correction to move pci_bus_put() to
pci_release_dev() instead.
