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

tty: USB serial termios bits

2009-09-19T20:13:33Z

Various drivers have hacks to mangle termios structures. This stems from the fact there is no nice setup hook for configuring the termios settings when the port is created Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

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

USB: remove use of err() in drivers/usb/serial

2008-10-17T21:41:10Z

err() is going away, so switch to dev_err() or printk() if it's really needed. Signed-off-by: Greg Kroah-Hartman

USB: remove info() macro from usb/serial drivers

2008-10-17T21:41:09Z

USB should not be having it's own printk macros, so remove info() and use the system-wide standard of dev_info() wherever possible. Signed-off-by: Greg Kroah-Hartman

tty: usb-serial krefs

2008-10-13T16:51:41Z

Use kref in the USB serial drivers so that we don't free tty structures from under the URB receive handlers as has historically been the case if you were unlucky. This also gives us a framework for general tty drivers to use tty_port objects and refcount. Contains two err->dev_err changes merged together to fix clashes in the -next tree.
