USB debug port only supports 8 byte rx/tx packets. Although spec implies that
"if a packet larger than eight bytes is received from the remote computer, the
device must break the larger packet into eight-byte packets before sending the
data to the Debug Port", the real PLX NET20DC device does not handle it right -
data is corrupted on debug port end if serial interface sends >8 byte urbs.
Patch below fixes the issue by limiting tx urb to 8 byte.

The get/set 2101_config helpers take an unsigned int rather than an
int. It is safe to change these in each case and may even produce
better code as it will be an unsigned divide rather than a signed
divide in places. All other manipulation was setting/masking bits
which will not be affected by the sign change.

The cypress app note for the M8 states that for the USB low speed
version of the part, throughput is effectively limited to 800
bytes/sec. So if we were to try a faster baud rate in such cases then
we risk overrun errors on receive. Best to just identify this case
and limit the rate to 4800 baud or less (by ignoring any request to
set a faster rate). The old baud rate setting code was somewhat
fragile; this change also hopefully makes it easier in the future to
better checking / limiting.

Remove a NULL check in cypress_m8; the check is useless in this

the kernel would be oops'ed before reaching this point anyway. (And

cypress_m8: Packet format is separate from characteristic size
The Cypress app note states that when using an 8 byte packet buffer
size that the packet format is modified (to be more compact). However
I have since discovered that newer DeLorme Earthmate LT-20 devices
(those that are low speed USB with 8 byte packet size) STILL use the
format that is really supposed to correspond to 32 byte packets.
Further confusing things is the subsequent discovery that there are
actually two different types of LT-20 - older LT-20's use 32 byte
packets which is probably why this issue wasn't originally
encountered. The solution here is to flag the packet format
separately from the buffer size. Then at initialization time,
identify the correct combination and set it up. This is a critical
fix for anyone with a newer LT-20. Older devices and non-Earthmate
devices should remain unaffected by this change. (If other devices
behave in this, uh, unexpected manner, it's now just a simple 1 line
change to fix them as well (change the pkt_fmt member for that
device). Default behavior with this patch is still to drive the
format as per the app-note; of course for Earthmate devices this is
overridden.

cypress_m8: Feature buffer fixes
From: Mike Isely <isely@pobox.com>
Don't hardcode the feature buffer size; use sizeof() instead. That
way we can easily specify the size in a single spot. Speaking of the
feature buffer size, the Cypress app note (and further testing with a
DeLorme Earthmate) suggests that this size should be 5 not 8 bytes.

None of these files use any of the functionality promised by
asm/semaphore.h. It's possible that they rely on it dragging in some
unrelated header file, but I can't build all these files, so we'll have
fix any build failures as they come up.

The num_interrupt_in, num_bulk_in, and other checks in the usb-serial
code are just wrong, there are too many different devices out there with
different numbers of endpoints. We need to just be sticking with the
device ids instead of trying to catch this kind of thing. It broke too
many different devices.
This fixes a large number of usb-serial devices to get them working
properly again.

Fixes the keyspan driver after the addition of additional
checking of driver requirements introduced in usb-serial.c
commit 063a2da8f0. The initialization
of the keyspan usb_serial_driver structs were not initializing the
num_interrupt_out field and the additional checking was rejecting
the end point so the driver wouldn't finish initializing.
This commit initializes the fields to NUM_DONT_CARE.
It works for the keyspan USA-49WG and doesn't break the USA-19HS
which are the two keyspan devices I have to test with.

Fixes a bug/inconsistency revealed by the additional sanity checking in
commit 063a2da8f0
introduced in the original 2.6.24 branch.
The Handspring Visor / PalmOS 4 device structure defines .num_bulk_out=2
but the usb-serial probe returns num_bulk_out=3, triggering the check in
the above commit and forcing a bail out when the device (a Garmin iQue in
my case) attempts to connect. The patch bumps the expected number of
endpoints to 3.
FWIW, this patch will probably solve the following kernel bug report for
Treo users (identical symptoms, different model PalmOS units):

The changes introduced in commit
063a2da8f0 changed the semantics of the
num_interrupt_in, num_interrupt_out, num_bulk_in and num_bulk_out
entries of the usb_serial_driver struct to be the number of endpoints
the device has when probed.
This patch changes the ti_1port_device usb_serial_driver struct to
reflect this change. The single port devices only have 1
bulk_out endpoint in their initial configuration, and so this patch
changes the number of other types to NUM_DONT_CARE.
The same change probably needs doing to the ti_2port_device struct,
but I don't have a two port device at hand.

Nobody should be using the generic usb-serial for anything other than
testing. Still, it's not a good thing that it's easy to lock up. There
is a traceback from NMI oopser here:
https://bugzilla.redhat.com/show_bug.cgi?id=431379
But in short, if a line discipline has a chance to echo anything, input
can loop back a write method. So, don't call tty_flip_buffer_push from
under a lock taken on write path.

Move the Onda H600/ZTE MF33 device from the sierra driver to the option

The reason it was moved is because the sierra driver is starting to support
more and more sierra proprietary features, so it makes more sense to keep
sierra only devices in there.
