un-/register a workqueue item only if a lowlevel driver supplies a

go and cancel all the queued work. However, the workqueue unreg happens
based on the ->op_state setting, and edac_mc_del_mc() sets this to
OP_OFFLINE _before_ we cancel the work item, leading to NULL ptr oops on
the workqueue list.
Fix it by putting the unreg stuff in proper order.

Due to the nature of i7core, we need to probe and attach all PCI
devices used by this driver during the first time probe is called.
However, PCI core will call the probe routine one time for each CPU
socket. If we return -EINVAL to those calls, it would seem that the
driver fails, when, in fact, there's no more devices left to initialize.
Changing the return code to -ENODEV solves this issue.

That's a nasty bug that took me a lot of time to track, and whose
solution took just one line to solve. The best fragrances and the worse
poisons are shipped on the smalest bottles.
The drivers/pci/quick.c implements the pci_get_device function. The normal
behavior is that you call it, the function returns you a pdev pointer
and increment pdev->kobj.kref.refcount of the pci device. However,
if you want to keep searching an object, you need to pass the previous
pdev function to the search.
When you use a not null pointer to pdev "from" field, pci_get_device
will decrement pdev->kobj.kref.refcount, assuming that the driver won't
be using the previous pdev.
The solution is simple: we just need to call pci_dev_get() manually,
for the pdev's that the driver will actually use.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
Probably due to a bug or some testing logic at PCI level, device
refcount for <bus>:00.0 device is decremented at the end of the
pci_get_device, made by i7core_get_all_devices(). The fact is that
the first versions of the driver relied on those devices to probe
for Nehalem, but the current versions don't use it at all.
So, let's just remove those devices from the driver, making it simpler
and fixing the bug.

This is a nasty bug. Since kobject count will be reduced by zero by

mci memory will be freed automatically. So, all we have left is ctl_name,
as shown by enabling debug:

Also, kfree(mci) shouldn't happen at the kobj.release, as it happens
when edac_remove_sysfs_mci_device() is called, but the logic is:
edac_remove_sysfs_mci_device(mci);
edac_printk(KERN_INFO, EDAC_MC,
"Removed device %d for %s %s: DEV %s\n", mci->mc_idx,
mci->mod_name, mci->ctl_name, edac_dev_name(mci));
