OK, so I'll do two patches instead of squashing everything on one patch.

Btw, as far as I see wee are zeroifying tty_struct always twice,
first in alloc_tty_struct and then in initialize_tty_struct again.
And alloc_tty_struct + initialize_tty_struct always used as a tuple
in current code, so I presume they might be squashed in one helper
instead to eliminate overhead, but it's different task.
