Message-Id: <1330990329-8566-1-git-send-email-broonie@opensource.wolfsonmicro.com> Date: Mon, 5 Mar 2012 23:32:09 +0000 From: Mark Brown <broonie@...nsource.wolfsonmicro.com> To: linux-kernel@...r.kernel.org Cc: patches@...nsource.wolfsonmicro.com, Mark Brown <broonie@...nsource.wolfsonmicro.com> Subject: [PATCH] regcache: Make sure we sync register 0 in an rbtree cache 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.
