USB: ir-usb: fix incorrect write-buffer length

2010-05-20T20:21:50+00:00

Returned length should include header length.

USB: ir-usb: fix set_termios race

2010-05-20T20:21:45+00:00

Use dynamically allocated urb for baudrate changes rather than
unconditionally submitting the port write urb which may already be in
use.

Compile-only tested.

USB: ir-usb: allow custom bulk buffer size without reallocation

2010-05-20T20:21:45+00:00

Use usb_serial_driver bulk_in_size and bulk_out_size to make sure
buffers of appropriate sizes are allocated in the first place rather than
reallocating them at every open.

USB: ir-usb: fix double free

2010-05-20T20:21:45+00:00

If the user specifies a custom bulk buffer size we get a double free at
port release.

USB: remove references to port->port.count from the serial drivers

2010-03-02T22:55:12+00:00

This patch (as1344) removes references to port->port.count from the
USB serial drivers.  Now that serial ports are properly reference
counted, port.count checking is unnecessary and incorrect.  Drivers
should assume that the port is in use from the time the open method
runs until the close method is called.

USB: tty: Prune uses of tty_request_room in the USB layer

2010-03-02T22:55:12+00:00

We have lots of callers that do not need to do this in the first place.
Remove the calls as they both cost CPU and for big buffers can mess up the
multi-page allocation avoidance.

USB serial: make USB device id constant

2010-03-02T22:54:16+00:00

The id_table field of the struct usb_device_id is constant in 
so it is worth to make the initialization data also constant.

The semantic match that finds this kind of pattern is as follows:

tty: USB does not need the filp argument in the drivers

2009-09-19T20:13:26+00:00

And indeed none of them use it. Clean this up as it will make moving to a
standard open method rather easier.

tty: Bring the usb tty port structure into more use

2009-06-11T15:50:56+00:00

This allows us to clean stuff up, but is probably also going to cause
some app breakage with buggy apps as we now implement proper POSIX behaviour
for USB ports matching all the other ports. This does also mean other apps
that break on USB will now work properly.
