The following series of patches addresses numerous issues that have cropped up recently in the interface between usb-serial and the TTY core. Considerable recent churn in the core, combined with the fact that the two never were entirely compatible, has created a number of problems. These manifest mostly in failures (or oopses) when a serial device is unplugged while the device file is open, or when a serial driver module is unloaded, or when a driver is re-loaded. I won't describe the details of the fixes here. None of them affect data transmission or line disciplines; they are all directed toward lifetime and reference counting issues. Note that one or more of these patches (especially 6/9) will clash with the tty-fix-regression-caused-by-tty-make-the-kref-destructor-occur-asynchronously patch, which is currently in mmotm but not yet merged into gregkh-all. Let me know when the time comes to resolve the conflicts, since the correct solution isn't obvious. Since Alan Cox is no longer the TTY maintainer, I'm not going to CC him. However if he happens to notice these changes while browsing the linux-usb list, I certainly wouldn't object to a little review and commentary (or criticism).
