The way airo.c keeps track of all its devices is complicated and buggy
as well (del_airo_dev forgets to free the memory add_airo_dev allocates).
It's cleaner to use the standard list primitives.
While we're at it, it's not necessary to put PCI cards in the list, because
the kernel already keeps track of them. We can take advantage of it and
use the .remove callback as it was meant to be.

sis900: Allocate rx replacement buffer before rx operation
Just found a hole in my last patch. It was reported to me that shortly after we
integrated this patch. The report was of an oops that took place inside of
netif_rx when using the sis900 driver. Looking at my origional patch I noted
that there was a spot between the new skb_alloc and the refill_rx_ring label
where skb got reassigned to the pointer currently held in the rx_ring for the
purposes of receiveing the frame. The result of this is however that the buffer
that gets passed to netif_rx (if it is called), then gets placed right back into
the rx_ring. So if you receive frames fast enough the skb being processed by
the network stack can get corrupted. The reporter is testing out the fix I've
written for this below (I'm not near my hardware at the moment to test myself),
but I wanted to post it for review ASAP. I'll post test results when I hear
them, but I think this is a pretty straightforward fix. It just uses a separate
pointer to do the rx operation, so that we don't improperly reassign the pointer
that we use to refill the rx ring.

USB: iowarrior.c: timeouts too small in usb_control_msg calls
The driver uses usb_control_msg() for exchanging data with the device.
When the driver lived freeley _outside_ the kernel tree (pre 2.6.21) the
timeouts for these calls where set to 5*HZ for reading, 1HZ for writing.
(These timeouts seemed to work fine for all users of the driver, at
least nobody complained in the last 2 years.
The current code (2.6.21-rc5) removed the 'HZ' from the timeouts and
left the driver with 5 jiffies for reading and 1 jiffy for writing. My
new machine is fast, but not that fast.
The patch also removes a useless debug statement, which was left over
from testing a broken firmware version

Add the "bus zero" feature to the usbmon. If a user process specifies bus
with number zero, it receives events from all buses. This is useful when
we wish to see initial enumeration when a bus is created, typically after

be open, then start capturing on it. This procedure was cumbersome and
could lose initial events. Also, often it's too bothersome to find exactly

USB: add "last_busy" field for use in autosuspend
This patch (as877) adds a "last_busy" field to struct usb_device, for
use by the autosuspend framework. Now if an autosuspend call comes at
a time when the device isn't busy but hasn't yet been idle for long
enough, the timer can be set to exactly the desired value. And we
will be ready to handle things like HID drivers, which can't maintain
a useful usage count and must rely on the time-of-last-use to decide
when to autosuspend.
The patch also makes some related minor improvements:
Move the calls to the autosuspend condition-checking routine
into usb_suspend_both(), which is the only place where it
really matters.
If the autosuspend timer is already running, don't stop
and restart it.
Replace immediate returns with gotos so that the optional
debugging ouput won't be bypassed.
If autoresume is disabled but the device is already awake,
don't return an error for an autoresume call.
Don't try to autoresume a device if it isn't suspended.
(Yes, this undercuts the previous change -- so sue me.)
Don't duplicate existing code in the autosuspend work routine.
Fix the kerneldoc in usb_autopm_put_interface(): If an
autoresume call fails, the usage counter is left unchanged.

USB: fix omninet write vs. close race
omninet kills all URBs in close. However write() returns as soon as
the URB has been submitted. Killing the last URB means a race that
can lose that date written in the last call to write().
As a fix this is moved to shutdown().

USB: fix catc error handling
this driver ignores errors while starting the transmit queue. It will
never be reported stopped as the completion handler won't run
and it will never be started again as it will be considered started.
