linux-next: manual merge of the net-next tree with the pci tree
Hi all,
Today's linux-next merge of the net-next tree got conflicts in:
drivers/pci/Kconfig
drivers/pci/controller/pci-hyperv.c
between commit:
f58ba5e3f686 ("PCI: pci-hyperv: Fix build errors on non-SYSFS config")
44b1ece783ff ("PCI: hv: Detect and fix Hyper-V PCI domain number collision")
from the pci tree and commit:
348dd93e40c1 ("PCI: hv: Add a Hyper-V PCI interface driver for software
backchannel interface")
from the net-next tree.
I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Thanks, the fix looks good to me. I guess there's nothing I can do at
the moment and Linus needs to fix this when he pulls from Dave (or
Bjorn, whichever is the last)?

linux-next: manual merge of the net-next tree with the pci tree
Hi all,
Today's linux-next merge of the net-next tree got a conflict in:
include/linux/pci_ids.h
between commit:

from the pci tree and commit:

I fixed it up (the former was just a superset of the latter, so I used
that) and can carry the fix as necessary (no action is required).

linux-next: manual merge of the net-next tree with the pci tree
Hi all,
Today's linux-next merge of the net-next tree got a conflict in
drivers/net/wireless/iwlwifi/pcie/trans.c between commit b9d146e30a2d
("iwlwifi: collapse wrapper for pcie_capability_read_word()") from the
pci tree and commit 7afe3705cd4e ("iwlwifi: continue clean up -
pcie/trans.c") from the net-next tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
