Subjectreview: 2.5.59 patches to fix bug 282

Please review these changes (following what gregkh has already
done in the usb dir). These fix bug number 282 at:
http://bugme.osdl.org and are tty cleanups to fix a module
race condition and utilize the new owner field of the tty_driver
structure.

I have not compiled yet so just a brief review is ok.

Thanks.

Hanna
hannal@us.ibm.com
included is a gzipped tar ball and the text below, they are the same code.
