[ NOTE! This merge effective drops commit 4329b93b28 ("of: Reduce

The of_graph_get_next_endpoint() function was moved and renamed by
commit fd9fdb78a9 ("[media] of: move graph helpers from
drivers/media/v4l2-core to drivers/of"). It was originally called
v4l2_of_get_next_endpoint() and lived in the file
drivers/media/v4l2-core/v4l2-of.c.
In that original location, it was then fixed to support empty port
nodes by commit b9db140c1e ("[media] v4l: of: Support empty port
nodes"), and that commit clashes badly with the dropped "Reduce
intendation" commit. I had to choose one or the other, and decided
that the "Support empty port nodes" commit was more important ]

pci_get_device() decrements the reference count of "from" (last
argument) so when we break off the loop successfully we have only one
device reference - and we don't know which device we have. If we want
a reference to each device, we must take them explicitly and let
the pci_get_device() walk complete to avoid duplicate references.
This is serious, as over-putting device references will cause
the device to eventually disappear. Without this fix, the kernel
crashes after a few insmod/rmmod cycles.

The reference count changes done by pci_get_device can be a little
misleading when the usage diverges from the most common scheme. The
reference count of the device passed as the last parameter is always
decreased, even if the function returns no new device. So if we are
going to try alternative device IDs, we must manually increment the
device reference count before each retry. If we don't, we end up
decreasing the reference count, and after a few modprobe/rmmod cycles
the PCI devices will vanish.
In other words and as Alan put it: without this fix the EDAC code
corrupts the PCI device list.

* tag 'edac_for_3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp:
EDAC: Don't try to cancel workqueue when it's never setup
e752x_edac: Fix pci_dev usage count
sb_edac: Mark get_mci_for_node_id as static
EDAC: Mark edac_create_debug_nodes as static
amd64_edac: Remove "amd64" prefix from static functions
amd64_edac: Simplify code around decode_bus_error
amd64_edac: Mark amd64_decode_bus_error as static
EDAC: Remove DEFINE_PCI_DEVICE_TABLE macro
amd64_edac: Fix condition to verify max channels allowed for F15 M30h
edac/85xx: Add PCIe error interrupt edac support
We only setup a workqueue for edac devices that use the polling
method. We still try to cancel the workqueue if an edac_device
uses the irq method though. This causes a warning from debug
objects when we remove an edac device:

In case the device 0, function 1 is not found using pci_get_device(),
pci_scan_single_device() will be used but, differently than
pci_get_device(), it allocates a pci_dev but doesn't does bump the usage
count on the pci_dev and after few module removals and loads the pci_dev
will be freed.

This patch marks the function get_mci_for_node_id() as static because it
is not used outside of sb_edac.c.
Thus, it also eliminates the following warning:
