This patch adds support for Dell Computer Corp. Wireless 5720 VZW Mobile
Broadband (EVDO Rev-A) Minicard GPS Port. I stole the name from lsusb,
but my card does not have a GPS on it (at least not that I can make
function). I'm sure the patch is whitespace damaged but the one line
addition should be fairly straightforward nonetheless.Tested-by: Rick Farina

- add FTDI device IDs for several ELV devices and NXTCam of Lego Mindstorms NXT
- add hopefully helpful new_id comment
- remove less helpful "Due to many user requests for multiple ELV devices we enable
them by default." comment (we simply add _all_ known devices - an
enduser shouldn't have to fiddle with obscure module parameters...).
- add myself to DRIVER_AUTHORThe missing NXTCam ID has been found at

added new device pid (PAPOUCH_AD4USB_PID) to ftdi_sio.h and ftdi_sio.c
AD4USB measuring converter is a 4-input A/D converter which enables the
user to measure to four current inputs ranging from 0(4) to 20 mA or
voltage between 0 and 10 V. The measured values are then transferred to
a superior system in digital form. The AD4USB communicates via USB.
Powered is also via USB. datasheet in english is here:

715b1dc01fe44537e8fce9566e4bb48d6821d84b ("USB: usb_debug,
usb_generic_serial: implement multi urb write").URB transfer buffer was never freed when using multi-urb writes.

This is a (almost) sort-only patch to sort FTDI device
product ID definitions in new ftdi_sio_ids.h header.Advantage is that new device ID submissions will now have a specific (sorted)
position - less future merge conflicts.Compile-tested, based on _current_ mainline git.
Minor checkpatch.pl warnings were eliminated whereever it made sense,
very minor text changes.Signed-off-by: Andreas Mohr

This is a strictly move-only patch to relocate all FTDI device
product ID definitions to their own ftdi_sio_ids.h header
(following the usual *_ids.h kernel tree convention, too),
thus correcting the slightly too messy appearance
(crucial driver defines were stuck somewhere in the decaying middle swamp
of the huge existing header).Compile-tested, based on latest mainline git.

This is a new generic kernel FIFO implementation.
The current kernel fifo API is not very widely used, because it has to
many constrains. Only 17 files in the current 2.6.31-rc5 used it.
FIFO's are like list's a very basic thing and a kfifo API which handles
the most use case would save a lot of development time and memory
resources.I think this are the reasons why kfifo is not in use:
- The API is to simple, important functions are missing
- A fifo can be only allocated dynamically
- There is a requirement of a spinlock whether you need it or not
- There is no support for data records inside a fifoSo I decided to extend the kfifo in a more generic way without blowing up
the API to much. The new API has the following benefits:- Generic usage: For kernel internal use and/or device driver.
- Provide an API for the most use case.
- Slim API: The whole API provides 25 functions.
- Linux style habit.
- DECLARE_KFIFO, DEFINE_KFIFO and INIT_KFIFO Macros
- Direct copy_to_user from the fifo and copy_from_user into the fifo.
- The kfifo itself is an in place member of the using data structure, this save an
indirection access and does not waste the kernel allocator.
- Lockless access: if only one reader and one writer is active on the fifo,
which is the common use case, no additional locking is necessary.
- Remove spinlock - give the user the freedom of choice what kind of locking to use if
one is required.
- Ability to handle records. Three type of records are supported:
- Variable length records between 0-255 bytes, with a record size
field of 1 bytes.
- Variable length records between 0-65535 bytes, with a record size
field of 2 bytes.
- Fixed size records, which no record size field.
- Preserve memory resource.
- Performance!
- Easy to use!This patch:
Since most users want to have the kfifo as part of another object,
reorganize the code to allow including struct kfifo in another data
structure. This requires changing the kfifo_alloc and kfifo_init
prototypes so that we pass an existing kfifo pointer into them. This
patch changes the implementation and all existing users.[akpm@linux-foundation.org: fix warning]

This patch deals with reducing the memory footprint for sierra driver.
This optimization is aimed for embedded software customers.Some sierra modems can expose upwards of 7 USB interfaces, each possibly
offering different services. In general, interfaces used for the
exchange of wireless data require much higher throughput, hence require
more memory (i.e. more URBs) than lower performance interfaces. URBs
used for the IN direction are pre-allocated by the driver and this patch
introduces a way to configure the number of IN URBs allocated on a
per-interface basis. Interfaces with lower throughput requirements
receive fewer URBs, thereby reducing the RAM memory consumed by the
driver.NOTE1: This driver has always pre-allocated URBs for the IN direction.
NOTE2: The number of URBs pre-allocated for the low-performance
interfaces has already been extensively tested in previous versions of
this driver.We also added the capability to log function calls by adding DEBUG flag.
Please note that this flag is commented out because this is the default
state
for it.Signed-off-by: Elina Pasheva

This patch adds the vendor and device id for the Mobilcom Debitel UMTS surf
stick (a.k.a. 4G Systems XSStick W14, MobiData MBD-200HU, ...).To see these ids, you need to switch the stick to modem operation first
with the help of usb_modeswitch. This makes it switch from 1c9e:f000 to
1c9e:9603 and thus be recognized by the option driver.Signed-off-by: Gernot Hillier

The use of urb->actual_length to update tx_outstanding_bytes
implicitly assumes that the number of bytes actually written is the
same as the number of bytes we tried to write. On error that
assumption is violated so just use transfer_buffer_length the number
of bytes we intended to write to the device.If an error occurs we need to fall through and call
usb_serial_port_softint to wake up processes waiting in
tty_wait_until_sent.Signed-off-by: Eric W. Biederman
