[PATCH]: Fix Ultrastor asm snippet

From: Samuel Thibault
Date: Wed May 18 2011 - 11:06:12 EST

Commit 1292500b replaced

"=m" (*field) : "1" (*field)


"=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.
