From b68e31d0ebbcc909d1941f9f230c9d062a3a13d3 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Mon, 2 Oct 2006 02:17:18 -0700 Subject: [PATCH] const struct tty_operations As part of an SMP cleanliness pass over UML, I consted a bunch of structures in order to not have to document their locking. One of these structures was a struct tty_operations. In order to const it in UML without introducing compiler complaints, the declaration of tty_set_operations needs to be changed, and then all of its callers need to be fixed. This patch declares all struct tty_operations in the tree as const. In all cases, they are static and used only as input to tty_set_operations. As an extra check, I ran an i386 allyesconfig build which produced no extra warnings. 53 drivers are affected. I checked the history of a bunch of them, and in most cases, there have been only a handful of maintenance changes in the last six months. serial_core.c was the busiest one that I looked at.
