From cdc57472dcc2ddc440545bde26791a11b42232b6 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 29 Nov 2017 19:46:26 +1100 Subject: pci: Add pci_dev_bus_num() helper A fair proportion of the users of pci_bus_num() want to get the bus number on a specific device, so first have to look up the bus from the device then call it. This adds a helper to do that (since we're going to make looking up the bus slightly more verbose). Signed-off-by: David Gibson Reviewed-by: Michael S. Tsirkin Signed-off-by: Michael S.
