TTY changes for 2.5.69

PATCH 1/1 TTY changes for 2.5.69
Here are some TTY changesets that do two different things TTY related things:
- fix the MOD_DEC/MOD_INC warnings for a number of tty drivers. These patches were previously sent to the Trivial Patch Monkey, but seem to have disappeared in its bowels somewhere, never to be seen again. These are the majority of the changes (25 different patches), and were all written by Hanna Linder.
- Make the tty class code actually work. With these changes, the /sys/class/tty directory shows all current tty devices, along with their device numbers, and a link to their device in the sysfs tree, if it has a physical location in that tree. Yeah, the implementation of yet another list of devices within the tty core isn't the nicest, but until the tty layer switches over to having tty devices in memory before they are opened (like all other device subsystems), this is necessary. For 2.7, this extra list will go away.
Please pull from:
bk://kernel.bkbits.net/gregkh/linux/tty-2.5
Patches will be posted as a followup to lkml.
thanks,
greg k-h
