sysfs: fix drivers/pci so if an attribute does not implement
show or store method read/write will return -EIO
instead of 0.

Here's a patch that fixes up the pci_dev refcounting in the CPCI code.
I've done some testing against it and it seems fine here.

Here is my third attempt at a patch to further update the CompactPCI
hotplug driver infrastructure to address the pci_enable_device issue
discussed on the list as well as a few other issues I discovered during
some more testing. This version addresses a few more issues pointed out
by Prarit Bhargava. Changes include:
- cpci_enable_device and its recursive calling of pci_enable_device on
new devices removed.
- Use list_rwsem to avoid slot status change races between disable_slot
and check_slots.
- Fixed oopsing in cpci_hp_unregister_bus caused by calling list_del on
a slot after calling pci_hp_deregister.
- Removed kfree calls in cleanup_slots since release_slot will have
done it already.
- Reworked init_slots a bit to fix latch and adapter file updating on
subsequent calls to cpci_hp_start.
- Improved sanity checking in cpci_hp_register_controller.
- Now shut things down correctly in cpci_hotplug_exit.
- Switch to pci_get_slot instead of deprecated pci_find_slot.
- A bunch of CodingStyle fixes.

Current shpchp driver doesn't seem to program command register to
enable PERR and SERR properly. The following patch fixes this issue.

[PATCH] CPCI: update
I have finally done some work to update the CompactPCI hotplug driver to
fix some of the outstanding issues in 2.6:
- Added adapter and latch status ops so that those files will get created
by the current PCI hotplug core. This used to not be required, but
seems to be now after some of the sysfs rework in the core.
- Replaced slot list spinlock with a r/w semaphore to avoid any potential
issues with sleeping. This quiets all of the runtime warnings.
- Reworked interrupt driven hot extraction handling to remove need for a
polling operator for ENUM# status. There are a lot of boards that only
have an interrupt driven by ENUM#, so this lowers the bar to entry.
- Replaced pci_visit_dev usage with better use of the PCI core functions.
The new code is functionally equivalent to the previous code, but the
use of pci_enable_device on insert needs to be investigated further, as
I need to do some more testing to see if it is still necessary.

Here is a patch to fix the problem of echoing 1 to "power" file
to enabled slot causing the slot to power down, and echoing 0
to disabled slot causing shpchp_disabled_slot() to be called
twice. This problem was reported by kenji Kaneshige.
Thanks,
Dely

I fogot to remove the code that freed the memory in cleanup_slots().
Here is the new patch, which I have also taken care of the comment
by Eike to remove the cast in hotplug_slot->private.

Here are some spelling corrections for drivers/pci.
CONTROLER -> CONTROLLER
Regisetr -> Register
harware -> hardware
inital -> initial
Initilize -> Initialize
funtion -> function
funciton -> function
occured -> occurred

here is the patch that fixes the bug introduced by my previous patch which
already went into 2.6.12-rc2 and is likely to cause trouble is someone hits
one the else case here by accident.
Using the &= operation before the if statement destroys the information the
if asks for so we always go into the else branch.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
