The original code looks like this:
/* if interface was already added, bind now; else let
* the future device_add() bind it, bypassing probe()
*/
if (!list_empty (&dev->bus_list))
device_bind_driver(dev);
IOW, it's checking to see if the device is attached to the bus or not
and binding the driver if it is. It's checking the device's bus list,
which will only appear empty when the device has been initialized, but
not added. It depends way too much on the driver model internals, but it
seems to be the only way to do the weird crap they want to do with
interfaces.
When I converted it to use klists, I accidentally inverted the logic,
which led to bad things happening. This patch returns the check to its
orginal value.

This makes the EHCI driver spin a bit longer before concluding that the
port reset failed. "Obviously safe."
It allows some devices to enumerate that previously didn't. We've seen
a bunch of these problem reports recently, this will make some go away.
As reported by Michael Zapf <Michael.Zapf@uni-kassel.de>, some EHCI
controllers seem to take forever to finish port resets and produce
"port N reset error -110" type errors. Spinning a bit longer helps.

ftdi_sio: Avoid losing bytes at tty-ldisc.
This patch was originally developed by Daniel Smertnig. I
(Ian Abbott) made a few changes. It has been tested by both
Daniel and I, at least for raw, non-canonical receive data
processing.
Here is Daniel's original description of the patch:
===
During a project in which I was using a FTDI 232BM to
transmit data at relative high speeds (625kBit/s), I
noticed a problem where data was lost even if flow
control was enabled: The FTDI-Driver receives 512 Bytes
of data over USB at a time, which consists of 8 64-Byte
packets. Subtracting the 2 bytes of status information
included in each packet this gives 496 "real" data
bytes per read.
This data is passed (indirectly, via the flip buffers)
to the tty line discipline which takes care of
throttling when there the free buffer space reaches
TTY_THRESHOLD_THROTTLE (128). Because the FTDI driver
processes up to 496 bytes at a time, throttling won't
happen in time and the line discipline will discard the
remaining bytes.
To avoid this the patch passes data in 62-byte blocks
to the tty layer and checks the available space in the
ldisc-buffers. If there isn't enough free space,
processing the rest of the data is delayed using a
workqueue.
Note: The original problem should be easily
reproducible with a userspace program which does slow &
small reads.

This patch adds a new driver for "Option" cards. This is a GSM data card,
controlled by three "serial ports" which are connected via an OHCI adapter,
all located on an oversized PC-Card. It's sold by several GSM service
providers.
Traditionally, this card has been accessed via the standard serial driver
and appropriate vendor= and product= options. However, testing has
revealed several problems with this approach, including hung data transfers
and lost data blocks when receiving.
Therefore, I've written a separate driver.

Various fixes to the sl811-hcd driver:
* Fix small glitches that crept in during recent evolution of usbcore's hcd
glue layer, coupling endpoint state records to usbcore and active urbs.
(As noted by folk whose boards weren't stuck on 2.6.9 kernels...)
* Cope with various system-specific issues:
- Some configurations (e.g. a CF-card uses this chip) have iospace
addresses for the two registers, rather than memory mapped ones.
- Some configurations do interesting things with IRQs; maybe the
line is shared, or it doesn't support level triggering.
- Not all boards can drive the chip reset line in software.
* Address a potential race during unlinking.
* Tweak probe/remove section info to handle the case where this segment
of a platform bus is hotpluggable (e.g. CF card). (The basic problem
is that CONFIG_HOTPLUG is global, which is wrong since not all busses
can hotplug even on hotplug-friendly systems...) Also export the
driver, so that the CF driver can depend on it.
Also removed some annoying end-of-line whitespace.

The original pwc author raised some questions about the reverse
engineering of the decompressor algorithms used in the pwc driver.
Having done some detailed investigation it appears those concerns that
clean room policy was not followed are reasonable. I've also had a
friendly discussion with Philips to ask their view on this.
This removes the problem items of code which reduces the pwc
functionality in the kernel a little but leaves all the framework for
setup that will be needed for decompressors in user space (where they
eventually belong). This change set is designed to be the minimal risk
change set given that 2.6.12 is hopefully close to hand, with a view to
merging the much updated pwc code in 2.6.13 series kernels.
Someone else can then redo the decompressors properly (clean room) in
user space.
Note that while its easy to say that it should have been caught earlier,
but the violation was really only obvious to someone who had access to
both the proprietary source and the 'GPL' source.
There's a bigger Speedtouch update coming your way after 2.6.12 but in
the meantime, let's at least make it automatically resync if the DSL
signal is lost.
