From 0719e1d23aab3b445c823404fd1b8b027757bb0a Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Thu, 16 Dec 2010 00:19:00 +0100 Subject: Documentation/kbuild: add info that 'choice' can have a symbol name Changeset 5a1aa8a1 added the possibility to name a choice, and to have the same choice be defined multiple times. But the documentation was forgotten, so this updates it accordingly.
