Subject: [PATCH] USB: ipw: convert to usb-wwan framework

This patch allows the ipw driver to use the multibuffer
infrastructure of usb-wwan. This improves speed.

USB: ipw: clean up dtr-rts handling

2010-05-20T20:21:46+00:00

No need to raise dtr/rts in open as this is taken care of by tty layer.

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.

USB: removal of tty->low_latency hack dating back to the old serial code

2009-04-23T21:15:29+00:00

This removes tty->low_latency from all USB serial drivers that push
data into the tty layer at hard interrupt context. It's no longer needed
and actually harmful.
