4018294b53 of: Remove duplicate fields from of_platform_driver
.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver.  This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.

This patch is a pretty mechanical change.  The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial.  This patch looks big and scary because it touches so
many files, but it should be pretty safe.

ac1ececea9 i7core_edac: Add support for X5670
As reported by Vernon Mauery <vernux@us.ibm.com>, X5670 (Westmere-EP) uses a
different register for one of the uncore PCI devices. Add support for
it.

Those are the PCI ID's on this new chipset:

fe:00.0 0600: 8086:2c70 (rev 02)
fe:00.1 0600: 8086:2d81 (rev 02)
fe:02.0 0600: 8086:2d90 (rev 02)

fe:05.3 0600: 8086:2dab (rev 02)
fe:06.0 0600: 8086:2db0 (rev 02)
fe:06.1 0600: 8086:2db1 (rev 02)
fe:06.2 0600: 8086:2db2 (rev 02)
fe:06.3 0600: 8086:2db3 (rev 02)
(as usual, the same PCI devices repeat at ff: bus)

The PCI device 8086:2c70 is shown as:

fe:00.0 Host bridge: Intel Corporation QuickPath Architecture Generic
Non-core Registers (rev 02)

So, for this device to be recognized, it is only a matter of adding this
new PCI ID to the driver.

8a311e179e Always call i7core_[ur]dimm_check_mc_ecc_err
This fixes an error in function i7core_check_error

In commit ca9c90ba09 which converts the
driver to use double buffering, there is a change in the logic.  Before,
if mce_count was zero, it skipped over a couple of statements and
finished out with a call to the *check_mc_ecc_err function.  The current
code checks to see if mce_count is 0 and then exits.

This change reverts the behavior back to the original where if there are
no errors to report, we skip to the end and call the *check_mc_ecc_err
function.

This fix allows the driver to work again on my Nehalem based blades
again.

For registered dimms, however, the error counters are already being
displayed at:

So, there's no need to add any extra sysfs nodes.

22e6bcbdcf i7core_edac: change remove module strategy
The old remove module stragegy didn't work on devices with multiple
cores, since only one PCI device is used to open all mc's, due to
Nehalem nature.

Also, it were based at pdev value. However, this doesn't point to the
pci device used at mci->dev.

So, instead, it unregisters all devices at once, deleting them from the
device list.
