USB: Add Samsung SGH-I500/Android modem ID switch to visor driver

2011-02-17T18:30:23Z

[USB]Add Samsung SGH-I500/Android modem ID switch to visor driver Samsung decided to reuse USB ID of its old CDMA phone SGH-I500 for the modem part of some of their Android phones. At least Galaxy Spica is affected. This modem needs ACM driver and does not work with visor driver which binds the conflicting ID for SGH-I500. Because SGH-I500 is pretty an old hardware its best to add switch to visor driver in cause somebody still wants to use that phone with Linux. Note that this is needed only when using the Android phone as modem, not in USB storage or ADB mode. Signed-off-by: Maciej Szmigiero Cc: stable Signed-off-by: Greg Kroah-Hartman

USB: visor: fix initialisation of UX50/TH55 devices

2010-10-22T17:22:08Z

Fix regression introduced by commit 214916f2ec6701e1c9972f26c60b3dc37d3153c6 (USB: visor: reimplement using generic framework) which broke initialisation of UX50/TH55 devices that used re-mapped bulk-out endpoint addresses.

USB: visor: increase bulk-out buffer size

2010-05-20T20:21:48Z

Increase the bulk-out buffer size to avoid any regression in throughput after replacing the old writing scheme which used dynamic buffers (e.g. up to 2k). 256b has been determined to be a good choice for several drivers including ftdi_sio which used to have a more or less identical write implementation.

USB: visor: reimplement using generic framework

2010-05-20T20:21:48Z

Kill custom read and write implementations (dynamically allocated write urbs). Note that I chose to remove the stat module parameter which was supposed to keep count of the amount of data sent and received, but which has been broken for three years (since b308e74d9c708ee2a9af14fbe235e0a41216f4ed "USB: visor driver adapted to new tty buffering" -- bytes_in was incorrectly updated and was thus always reported as 0). Compile-only tested. Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: visor: fix memory leak

2010-05-20T20:21:48Z

Fix memory leak for some devices (Sony Clie 3.5) due to port private data not being freed on release. Cc: stable Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

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: serial: fix assumption that throttle/unthrottle cannot sleep

2009-10-09T20:52:09Z

many serial subdrivers are clearly written as if throttle/unthrottle cannot sleep. This leads to unneeded atomic submissions. This patch converts affected drivers in a way to makes very clear that throttle/unthrottle can sleep. Thus future misdesigns can be avoided and efficiency and reliability improved. This removes any such assumption using GFP_KERNEL and spin_lock_irq() Signed-off-by: Oliver Neukum Signed-off-by: Greg Kroah-Hartman
