From e46f5b6967b50e405de7463815e41613afcc321f Mon Sep 17 00:00:00 2001 From: Samuel Thibault Date: Wed, 18 May 2011 17:06:05 +0200 Subject: [PATCH] Fix Ultrastor asm snippet BugLink: http://bugs.launchpad.net/bugs/793702 commit fad4dab5e44e10acf6b0235e469cb8e773b58e31 upstream. Commit 1292500b replaced "=m" (*field) : "1" (*field) with "=m" (*field) : with comment "The following patch fixes it by using the '+' operator on the (*field) operand, marking it as read-write to gcc." '+' was actually forgotten. This really puts it.
