The USB serial code was a new user of the kfifo API, and it was missed
when porting things to the new kfifo API.
Please make the write_fifo in place. Here is my patch to fix the
regression and full ported version.

interface. In particular, the following details are added
- a struct for low level io functions (read/write)
- a priv field to be used as 'viewport' by low level access functions
- an (*init) and (*shutdown) callbacks, along with static inline helpers
- a (*set_vbus) callback to switch the port power on and off
- a flags field for per-transceiver settings
- some defines for the flags bitmask to configure platform specific
details

This patch (as1295) fixes a recently-added bug in the USB serial core.
If certain kinds of errors occur during probing, the core may call a
serial driver's release method without previously calling the attach
method. This causes some drivers (io_ti in particular) to perform an
invalid memory access.
The patch adds a new flag to keep track of whether or not attach has
been called.

On some EHCI usb debug controllers, the EHCI debug device will fail to
be seen after a port reset, after a warm reset. Two options exist to
get the device to initialize correctly.
Option 1 is to unplug and plug in the device.
Option 2 is to use the EHCI port test to get the usb debug device to
start talking again. At that point the debug controller port reset
will succeed.

If the EHCI debug port is initialized and in use, the EHCI host
controller driver must follow two rules.
1) If the EHCI host driver issues a controller reset, the debug
controller driver re-initialization must get called after the reset
is completed.
2) The EHCI host driver should ignore any requests to the physical
EHCI debug port when the EHCI debug port is in use.
The code to check for the debug port was moved from ehci_pci_reinit()
to ehci_pci_setup because it must get called prior to ehci_reset()
which will clear the debug port registers.

This patch implements several changes:
1) Improve the capability to debug the dbgp driver
The dbgp_ehci_status() was added in a number of places to report
the critical ehci registers to diagnose the cause of a failure of
the ehci-dbgp driver.
2) Capability to survive the host controller initialization
The dbgp_external_startup(), dbgp_not_safe, and dbgp_phys_port were
added so as to allow the ehci-dbgp to re-initialize after the ehci
host controller is reset by the standard host controller driver.
This same routine is common for the early startup or
re-initialization.
This resulted in the need to move some of the initialization code
out of the __init section because the ehci driver has the
possibility to be loaded later on as a kernel module.
3) Stability improvements for device initialization
The device enumeration from 0 to 127 has the possibility to fail
the first time after a warm reset on some older EHCI debug
controllers. The enumeration will be tried up to 3 times to
account for this failure case.
The dbg_wait_until_complete() was changed to wait up to 250 ms
before failing which only comes into play during device
initialization. The maximum delay will never get hit during the
course of normal operation of the driver, unless the device got
unplugged or there was a ehci controller failure, in which case the
dbgp device driver will shut itself down.

When do_output_char() attempts to write a carriage return/line feed sequence,
it first checks to see how much buffer room is available. If there are at least
two characters free, it will write the carriage return/line feed with two calls
to tty_put_char(). It calls the tty_operation functions write() for devices that
don't support the tty_operations function put_char(). If the USB generic serial
device's write URB is not in use, it will return the buffer size when asked how
much room is available. The write() of the carriage return will cause it to mark
the write URB busy, so the subsequent write() of the line feed will be ignored.
This patch uses the kfifo infrastructure to implement a write FIFO that
accurately returns the amount of space available in the buffer.

Usbnet framework assumes USB hardware doesn't handle zero length

This patch fixes an easily reproducible tx lockup when sending a frame
that results in exactly 512 bytes in a USB transmission (e.g. a UDP
frame with 458 data bytes, due to IP headers and our USB headers). It

The USB 3.0 bus specification added an "Endpoint Companion" descriptor that is
supposed to follow all SuperSpeed Endpoint descriptors. This descriptor is used
to extend the bus protocol to allow more packets to be sent to an endpoint per
"microframe". The word microframe was removed from the USB 3.0 specification
because the host controller does not send Start Of Frame (SOF) symbols down the
USB 3.0 wires.
The descriptor defines a bMaxBurst field, which indicates the number of packets
of wMaxPacketSize that a SuperSpeed device can send or recieve in a service
interval. All non-control endpoints may set this value as high as 16 packets
(bMaxBurst = 15).
The descriptor also allows isochronous endpoints to further specify that they
can send and receive multiple bursts per service interval. The bmAttributes
allows them to specify a "Mult" of up to 3 (bmAttributes = 2).
Bulk endpoints use bmAttributes to report the number of "Streams" they support.
This was an extension of the endpoint pipe concept to allow multiple mass
storage device commands to be outstanding for one bulk endpoint at a time. This
should allow USB 3.0 mass storage devices to support SCSI command queueing.
Bulk endpoints can say they support up to 2^16 (65,536) streams.
The information in the endpoint companion descriptor must be stored with the
other device, config, interface, and endpoint descriptors because the host
controller needs to access them quickly, and we need to install some default
values if a SuperSpeed device doesn't provide an endpoint companion descriptor.

Modify the USB core to handle the new USB 3.0 speed, "SuperSpeed". This
is 5.0 Gbps (wire speed). There are probably more places that check for
speed that I've missed.
SuperSpeed devices have a 512 byte endpoint 0 max packet size. This shows
up as a bMaxPacketSize0 set to 0x09 (see table 9-8 of the USB 3.0 bus
spec).
xHCI spec says that the xHC can handle intervals up to 2^15 microframes. That
might change when real silicon becomes available.
Add FIXME note for SuperSpeed isochronous endpoints. They can transmit up
to 16 packets in one "burst" before they wait for an acknowledgment of the
packets. They can do up to 3 bursts per microframe (determined by the
mult value in the endpoint companion descriptor). The xHCI driver doesn't
have support for isoc yet, so fix this later.

controller driver.
* Langwell and Moorestown are names used in development. They are not
approved official name.
Note:
This patch is the first version Intel Langwell USB OTG Transceiver
driver. The development is not finished, and the bug fixing is on going
for some hardware and software issues. The main purpose of this
submission is for code view.
Supported features:
- Data-line Pulsing SRP
- Support HNP to switch roles
