[PATCH] ehci, more small fixes

- some access to urb->hcpriv and urb->status needed to be
locked using urb->lock
- paranoia: don't depend on two values being in lock-step.

[PATCH] hub driver uses dev_info(), less log clutter

This patch converts most common hub diagnostics to use the
device model diagnostic macros ... not all, someone should
reduce the number of err() strings for "bogus hub" cases,
and ideally streamline some of the dozen or so "here's what's
special about this new hub" dbg() messages.

So the messages become more useful: they id the port (and
implicitly the device) involved, using a kernel-wide standard
convention. Size overhead is smaller too.

For folk running with USB debugging enabled, it also cuts
the useless chatter on connections by deleting the per-poll
success messages and a partial dup message when things change.
And it deletes a newish diagnostic on a (non-hub) unlink path.

It also makes Pete's new debounce message use the right
port number -- one-based, not zero-based.

My main issue with this patch is that it doesn't change
more messages, but it seems reasonable to merge it anyway.

[PATCH] usb-storage: fixup interpret_urb_result()

This patch fixes interpret_urb_result in two major ways:
(1) Uses a switch() instead of nested if() statements
(2) Handle -EREMOTEIO to indicate a short scatter-gather transfer

[PATCH] USB: PWC 8.10 for 2.5.51

Well, two patches in one... These patches will bring the PWC (Philips
Webcam) driver in both 2.4.20 and 2.5.51 up to version 8.10. Functionally,
the two branches are the same (about 70% of the code is shared), but the
differences in kernel architecture are too large to handle with a few
#ifdefs.

This patch fixes the following (this are only the differences between 8.9
and 8.10):

* Fixed ID for QuickCam Notebook pro
* Added GREALSIZE ioctl() call
* Fixed bug in case PWCX was not loaded and invalid size was set

typedef enum { .. } ParseState_t -> enum ParseState
typedef enum { .. } FrameState_t -> enum FrameState
typedef enum { .. } Deinterlace_t -> enum Deinterlace

[PATCH] ehci misc patches

small fixes flushed by the hunt for bigger game:

- terminate td lists with dummy, not list end marker
- use alt_next only for real short control reads
- un-halt async qhs before scheduling
- deletes unused debug code, pointless assignments
- surely nobody ever sees that memleak
- terminate two related "while" loops the same way

[PATCH] usbnet: zaurus, oops, etc

This patch:

- Removes Pavel's Zaurus-private crc32 code; the base patch
was from Pavel.

- Addresses two issues Toby Milne reported against the Zaurus:
(a) if skbs had extra framing added (z, net1080, gl620a),
the original size (now too small) was used on tx;
(b) added FLAG_FRAMING_Z so rx packets had enough space

- Removes an oops from the driver model conversion (saved
the wrong pointer). Disconnecting wasn't healthy.

- Forward-ports some ethtool support from the 2.4 version:
PDAs are always connected, so report them that way.

- Stubs in some PXA-250 support for non-Zaurus PDAs.
This is currently commented out; so far those PDAs
only run Linux for bleeding edge developers.

- Minor cleanups.

[PATCH] ehci-hcd (2/2): rest of tasklet remove

This is the rest of the work to remove the tasklet: the non-syntax
portions which affect work scheduling. It's not quite davem's version;
it's got locking updates, which among other things prevent a hang when
the timer kicks in.

This scheduling change is split out from the other parts in case more
problems like that unlink race (fixed in my previous patch) show up.
It doesn't fix (or help fix) any ehci bugs, but simpler code is fine.

[PATCH] ehci-hcd (1/2): portability (2.4), tasklet,

This should be innocuous; I expect most folk won't notice anything
better (or worse) from this patch unless they're using Intel EHCI.

removing tasklet
- parts of davem's patch (passing pt_regs down)
- remove 'max_completions'
- update cleanup after hc died
- fix an urb unlink oops (null ptr) that happens more often this way

talking to hardware
- fixes for some short read issues (may still be others)
* use qtd->hw_alt_next to stop qh processing after short reads
* detect/report short reads differently
- longer reset timeout (it was excessively short, broke Intel)

other
- simpler diagnostics portability to 2.4: wrap dev_err() etc
- urb unlink wait and non-wait unlink codepaths share most code
- don't try ehci_stop() in interrupt context (bug from hcd layer)
- minor stuff, including
* some "after hc died" paths were wrong
* verbose debug messages compile again
* don't break error irq count
