Subject: [PATCH] [PATCH] tty: cleanup release_mem

release_mem contains two copies of exactly the same code.  Refactor these
into a new helper, release_tty.  The only change in behaviour is that the
driver reference count is now decremented after the master tty has been
freed instead of before.

[penberg@cs.helsinki.fi: fix use-after-free in release_tty.]
