Subject: [PATCH] regcache: Make sure we sync register 0 in an rbtree cache
Date: Mon, 5 Mar 2012 23:32:09 +0000 [thread overview]
Message-ID: <1330990329-8566-1-git-send-email-broonie@opensource.wolfsonmicro.com> (raw)
Most of the current users have register 0 as a volatile register or don't
have a register 0 so it's not been apparent that it's not getting synced.
