USB: fix interface sysfs file-creation bug

This patch (as1005) fixes a rather subtle problem.  When
usb_set_configuration() registers the interfaces and their files in
sysfs, it doesn't expect those files to exist already.  But when an
interface is registered, its driver may call usb_set_interface() and
thereby cause the sysfs files to be created.  The result is an error

the NULL dereference is here:

 (gdb) list *0xffffffff804a9504
 0xffffffff804a9504 is in natsemi_poll (drivers/net/natsemi.c:717).
 712             return count;
 713     }
 714
 715     static inline void __iomem *ns_ioaddr(struct net_device *dev)
 716     {
 717             return (void __iomem *) dev->base_addr;
 718     }
 719

which is this code from natsemi.c:

 2227            struct net_device *dev = np->dev;
 2228            void __iomem * ioaddr = ns_ioaddr(dev);
 2229            int work_done = 0;

seems like the NAPI changes in -rc1 added an np->dev field but forgot to
initialize it ...

does the patch below fix the oops for you?

      [NET]: Make NAPI polling independent of struct net_device objects.

added np->dev to drivers/net/natsemi.c's struct netdev_private, but
forgot to initialize that new field upon driver init. The result was
a predictable NULL dereference oops the first time the hardware
generated an interrupt.

ahci: ahci: implement workaround for ASUS P5W-DH Deluxe ahci_broken_hardreset(), take #2

P5W-DH Deluxe has ICH9 which doesn't have PMP support but SIMG 4726
hardwired to the second port of AHCI controller at PCI device 1f.2.
The 4726 doesn't work as PMP but as a storage processor which can do
hardware RAID on downstream ports.

When no device is attached to the downstream port of the 4726, pseudo
ATA device for configuration appears.  Unfortunately, ATA emulation on
the device is very lousy and causes long hang during boot.

This patch implements workaround for the board.  If the mainboard is
P5W-DH Deluxe (matched using DMI), only hardreset is used on the
second port of AHCI controller @ 1f.2 and the hardreset doesn't depend
on receiving the first FIS and just proceed to IDENTIFY.

This workaround fixes bugzilla #8923.

libata: cosmetic clean up in ata_eh_reset()

Local variable @action usage in ata_eh_reset() is a bit confusing.
It's used only to cache ehc->i.action to test reset masks after
clearing it; however, due to the generic name "action", it's easy to
misinterpret the local variable as containing the selected reset
