From d281da7ff6f70efca0553c288bb883e8605b3862 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Thu, 16 Sep 2010 18:21:24 +0100 Subject: tty: Make tiocgicount a handler Dan Rosenberg noted that various drivers return the struct with uncleared fields. Instead of spending forever trying to stomp all the drivers that get it wrong (and every new driver) do the job in one place. This first patch adds the needed operations and hooks them up, including the needed USB midlayer and serial core plumbing.
