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

2011-06-26T16:46:48Z

commit acb52cb1613e1d3c8a8c650717cc51965c60d7d4 upstream. [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 Signed-off-by: Greg Kroah-Hartman Signed-off-by: Paul Gortmaker

commit 199b113978015309dd02c69844c19a1be3f4dbcf upstream. Fix memory leak for some devices (Sony Clie 3.5) due to port private data not being freed on release. Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

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

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

#define dbg adds the newline, messages shouldn't. Converted dbg("%s", "some string") to dbg("some string") Signed-off-by: Joe Perches Signed-off-by: Greg Kroah-Hartman

usb:usbserial:visor: fix race between unthrottle and completion handler visor_unthrottle() mustn't resubmit the URB unconditionally as the URB may still be running. the same bug as opticon. Signed-off-by: Oliver Neukum 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

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
