USB: ipaq.c: fix a timeout loop

2016-01-22T21:40:07Z

commit abdc9a3b4bac97add99e1d77dc6d28623afe682b upstream. The code expects the loop to end with "retries" set to zero but, because it is a post-op, it will end set to -1. I have fixed this by moving the decrement inside the loop. Fixes: 014aa2a3c32e ('USB: ipaq: minor ipaq_open() cleanup.')

Revert "USB: Adding support for HTC Smartphones to ipaq"

2010-08-10T21:35:35Z

ipaq already had this device id defined: { USB_DEVICE(0x0BB4, 0x00CF) }, /* HTC USB Modem */ Revert the commit which adds the duplicate entry. This reverts commit 04cab1329336d4577d6638360c905e360934b425. Originally-by: Ben Collins Signed-off-by: Leann Ogasawara Signed-off-by: Greg Kroah-Hartman

USB: ipaq: reimplement using generic framework

2010-05-20T20:21:48Z

Kill custom fifo, read and write implementations (single-urb and fifo, but still maintained list of 256*256b urb buffers per port). Compile-only tested. Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: serial: allow drivers to define bulk buffer sizes

2010-05-20T20:21:33Z

Allow drivers to define custom bulk in/out buffer sizes in struct usb_serial_driver. If not set, fall back to the default buffer size which matches the endpoint size. Three drivers are currently freeing the pre-allocated buffers and allocating larger ones to achieve this at port probe (ftdi_sio) or even at port open (ipaq and iuu_phoenix), which needless to say is suboptimal.

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

2010-03-02T22:55:12Z

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. Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

USB: ipaq: fix oops when device is plugged in

2009-10-09T20:52:07Z

This patch (as1293) fixes a problem with the ipaq serial driver. It tries to bind to all the interfaces, even those that don't have enough endpoints. The symptom is an invalid memory reference and oops when the device is plugged in.

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

2009-09-19T20:13:26Z

And indeed none of them use it. Clean this up as it will make moving to a standard open method rather easier. Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

USB: usb-serial: replace shutdown with disconnect, release

2009-06-16T04:44:47Z

This patch (as1254) splits up the shutdown method of usb_serial_driver into a disconnect and a release method. The problem is that the usb-serial core was calling shutdown during disconnect handling, but drivers didn't expect it to be called until after all the open file references had been closed. The result was an oops when the close method tried to use memory that had been deallocated by shutdown. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

tty: Bring the usb tty port structure into more use

2009-06-11T15:50:56Z

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. Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds

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

2009-04-23T21:15:29Z

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. Signed-off-by: Oliver Neukum Cc: Alan Cox Signed-off-by: Greg Kroah-Hartman
