Subject: [PATCH 0/9] tty: tty_struct dependency clean-ups
Date: Fri,  9 Sep 2016 17:37:01 -0500	[thread overview]
Message-ID: <20160909223711.26238-1-robh@kernel.org> (raw)

This patch series removes or prepares to remove some of the dependencies 
on tty_struct within tty_port drivers. This will allow using tty_ports 
directly for so called UART slave devices. 

The first patch fixes a regression from the last round with tty 
closing. Patches 2-4 are mechanical conversions generated with 
coccinelle. This is my first adventure into coccinelle, so hopefully I 
didn't screw things up. :) Only serial_core has some of its tty_struct 
dependencies removed as those are the drivers we immediately care about 
supporting slave devices with.

Next up after this are moving some functions to the tty_port ops. I've 
got some WIP patches for some of that, but nothing ready to send out 
quite yet.
