Jiri Slaby a9dccddb60 TTY: plug in deinitialize_tty_struct 
Used the newly introduced deinitialize_tty_struct to properly shut
down ldisc.

It is intended to fix the Julian's reported problem. He reports that
kmemleak checker warns about memory leak:
unreferenced object 0xc0e19860 (size 8):
comm cat, pid 1226, jiffies 4294919464 (age 287.476s)
hex dump (first 8 bytes):
44 de 2d c1 01 00 00 00 D.-.....

Jiri Slaby c18d77aa00 TTY: unify pty_unix98_install fail path handling 
Change it so that we call the deinit functions at one place at the end
of the function (by gotos). And while at it use some sane label names.

This is a preparation for the deinitialization of tty in the next
patch.

Arnd Bergmann 5edc341313 drivers: remove extraneous includes of smp_lock.h 
These were missed the last time I cleaned this up
globally, because of code moving around or new code
getting merged.

Alan Cox 6caa76b778 tty: now phase out the ioctl file pointer for good 
Only oddities here are a couple of drivers that bogusly called the ldisc
helpers instead of returning -ENOIOCTLCMD. Fix the bug and the rest goes
away.

Greg Kroah-Hartman 96fd7ce58f TTY: create drivers/tty and move the tty core files there 
The tty code should be in its own subdirectory and not in the char
driver with all of the cruft that is currently there.

Based on work done by Arnd Bergmann <arnd@arndb.de>
