From 9ed90d20449b01beb71a4e125d291a36c80c4ad4 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Mon, 16 Jan 2017 16:54:28 -0600 Subject: tty: move the non-file related parts of tty_release to new tty_release_struct For in-kernel tty users, we need to be able to create and destroy 'struct tty' that are not associated with a file. The creation side is fine, but tty_release() needs to be split into the file handle portion and the struct tty portion. Introduce a new function, tty_release_struct, to handle just the destroying of a struct tty.
