USB sddr55 minor patch to enable a MDSM-B reader
This was forgotten in the previous sddr55 patch import, and is needed
to support the MDSM-B reader devices.
Thanks to [EMAIL PROTECTED] for the 2.4.x version of the patch.

[PATCH] USB device reference counting api cleanup changes
This patch replaces the awkwardly named usb_inc_dev_use() and
usb_dec_dev_use() with usb_get_dev() and usb_put_dev() to match the
naming convention of the rest of the kernel's reference counted
structures. It also does away with the special case of usb_free_dev(),
and has usb_put_dev() be the same thing (through a #define, just like
usb_free_urb() works.)
Now when the last person calls usb_put_dev() or usb_free_dev() the
structure is cleaned up. This allows the different host controller
drivers to implement their logic differently if they want to (as they
do), and everyone can be happy and stop arguing about the "proper" way
to write their host controller drivers :)

[PATCH] USB device reference counting fix for uhci.c and usb core
Earlier in the 2.5 development cycle a patch was applied that changed
the reference counting behaviour for USB devices.
There are a couple of problems with the change:
- It made the USB code more complicated as a whole with the introduction
of an additional cleanup path for devices. Using the traditional method
of reference counting, cleanup is handled implictly
- It reduces functionality by requiring a callback for all references to
the device, but doesn't provide a method of providing callbacks for
references. It relies on the hardcoded device driver ->disconnect and
HCD ->deallocate method for callbacks
The traditional method of using reference counting supports as many
reference users as needed, without complicating it with mandatory
callbacks to cleanup references.
The change in 2.5 also only helps catch one subset of programming
problem in device drivers, the case where it decrements too many times.
That is of dubious debugging value.
So, this patch reverts the change and makes the reference counting
behave like it does in the rest of the kernel as well as how the USB
code does in 2.4.
This patch doesn't remove all of the superfluous code. Some drivers,
like usb-ohci, ohci-hcd and ehci-hcd have some code that is no longer
needed. I wanted to spend some more time with those drivers since the
changes weren't as trivial as uhci.c and usb-uhci.c.
I've tested with uhci and usb-ohci with no adverse effects.

[PATCH] usb_submit_urb fix for broken usb devices
added check for wMaxPacketSize of 0, which is a messed up device, but
seems to be legal according to the USB spec.
Thanks to Johannes for figuring out the problem, and providing an
original version of this patch.

[PATCH] usb-storage locking fixes
I found several SMP and UP locking errors in usb-storage, attached is a
patch:
Changes:
* srb->result is a bitfield, several << 1 were missing.
* add scsi_lock calls around midlayer calls, release the lock before
calling usb functions that might sleep.
* replace the queue semaphore with a queue spinlocks, queuecommand is
called from bh context.

[PATCH] uhci.c FSBR timeout
There was a discussion a long time ago about how safe the bit operations
were as well as recently.
set_bit/clear_bit are not safe on x86 UP, nor are they safe on other
architectures. It's also unclear from the UHCI spec if the HC's are safe
with respect to atomic updates to the status field.
This patch ditches all of the uses of set_bit and clear_bit and changes
the algorithm that depended on it.
The FSBR timeout algorithm would reenable FSBR for transfers when they
started making progress again. So instead of trying for this best case,
we convert the transfer over to depth first from the standard breadth
first. To make sure the transfer doesn't hog all of the bandwidth, every
5th TD is left in breadth first mode. This will ensure other transfers
get some bandwidth.
It's not perfect, but I think it's a good compromise.
Note: td->info is read only by the HC, so we can touch it whenever we
want.

[PATCH] -- hub/tt error recovery
This patch adds missing functionality to the transaction translator
support for USB 2.0 hubs:
- moves the 'struct usb_tt' definition to "hub.h" from <linux/usb.h>
- adds state to it as neeed for some control/bulk error recovery
- teaches the hub driver how to use that state (via keventd)
- adds a call letting HCDs trigger that recovery

[PATCH] -- ehci misc FIXMEs
This addresses FIXME comments in the EHCI code, notably:
- telling the hub driver to clear up TT error state
(relies on the hub error recovery patch I just sent)
- using 64bit PCI DMA where appropriate
- handling BIOS handoff as neeed
