[PATCH v4 1/5] PCI: pcibus address to resource converting take bus instead of dev

Yinghai Lu yinghai at kernel.org
Tue Dec 10 17:54:40 EST 2013


For allocating resource under bus path, we do not have dev to pass along,
and we only have bus to use instead.

-v2: drop pcibios_bus_addr_to_resource().
-v3: drop __* change requested by Bjorn.
