Here's a half-successful attempt. With this patch, the device no longer
appears twice, and it always works on the first open (at least, so I've
observed up to this point). The open following a successful open usually
fails (roughly speaking, it appears to play dead), and the open following
a failed open usually (always?) succeeds.

So, on my PL-2303, it's not perfect but it's certainly livable.

This patch is based on the one I did for 2.4, and in fact, this code
functions when it's plugged into 2.4.20-pre10 instead of 2.5.42. In that
scenario, the opens work 100% of the time.

I'd be interested in suggestions or comments regarding this patch.
Anyone who has a PL-2303 working under 2.5 might want to try this patch
just to make sure it doesn't kill their working setup.

Updates the vicam driver to the latest version from the sourceforge.net
project.

	On second thought after reading Oliver Neukum's question about
"shaving off a cycle or two", here is version of my fix for down()
being called from interrupt context that uses unlikely() to get the
speed advantage that would be available from BUG_ON(), while still
ensuring that the condition is executed even if assertions are
compiled out.

wacom.c generates the following warning:

drivers/usb/input/wacom.c: In function `wacom_probe':
drivers/usb/input/wacom.c:405: warning: unused variable `rep_data'

Hi, this patch fixes usbfs.  You can't use a single mount_count for 2
different mounts.

Here's the updated "nousb" patch for vanilla 2.5.41.
It applies with 2 small offsets to 2.5.41-bk3.

A couple patches on 2.5.41; issues discovered during QA.

1: The hack to get around the unlinking bug. You said this was also in
2.5.x, so I've included this.

2: filp is NULL when called from usb_serial_disconnect. Fixes an oops.

3: In the case where the module is reloaded; the endpoints in the
usbsubsystem don't go away. So when the module comes back, the
endpoints still have the unlink thing, and also need to be cleared.
Otherwise the firmware appears not respond to the version nubmer query
and the driver doesn't attach, and you have no device.

Rework lots of cruft in the aic7xxx_old driver so that it can be more
easily read and understood by other people and so it starts on the road
to giving a clearer picture of how to interact with the scsi mid layer.

This does 4 things.  Fixes the oversight James found about cmd_per_lun.
Makes scsi_adjust_queue_depth() implement the usage of tagged that I
described in my email to linux-scsi.  Updates some comments to highlight
things that are going to go away shortly.  Removes the call to
host->select_queue_depths() entirely since drivers that implement this
will try to set SDptr->queue_depth to the desired depth, which in reality
will do nothing but confuse the mid layer since that is now the actual
allocated command counter, so it won't make the mid layer allocate more
commands, it will make the mid layer think more commands have been
allocated.

Start removing items from scsi.h that are driver specific and provide a
patch to NCR53C9x.? that switches to driver private storage instead as
an example of how drivers should do private struct storage

Also fixes a bug when UTP port is unplugged.

Also some minor cleanups as well.

[This patch qualifies for the cavemen ugh-lympics, because the driver does
some really nasty things in interrupt context and this patch does
not correct that.  However, the patch is an incremental improvement
over the current code so it's still worth applying.  I'll fix it
further if IBM does not fix it first.  -jgarzik]

The reason Vojtech broke it was the stupid name of a field
in struct kbd_repeat, namely "rate".  Every sane person
expects that a rate has dimension [1/sec], but here the
"rate" is a time period measured in msec.

So, the patch below first of all fixes the code,
and secondly changes the name.
Since Vojtech used PERIOD as index, I also used period
as field name in the struct.

Half of the stuff below is actually from Alan Stern.

Andries

handling of flag bits, etc.

This fixes the scheduler's migration code to not disable preemption.  It
also fixes the bug that was hidden by the broken disable-preempt change:
the migration thread did not kick idle CPUs if a task is migrated to
them, which causes a hung boot when ksoftirqds are started.  It was pure
luck it worked until now, it was broken pretty much from day 1 on.

Quick fix for CONFIG_NLS, add a missing space.
