Subject: [PATCH 1/5] regmap: A cache type of _NONE behaves like a bypassed cache
Date: Mon, 19 Sep 2011 19:03:40 +0100 [thread overview]
Message-ID: <1316455424-11173-1-git-send-email-broonie@opensource.wolfsonmicro.com> (raw)
In-Reply-To: <20110919175948.GD540@opensource.wolfsonmicro.com>
Avoid extra special casing by setting the cache_bypass flag when we're
not caching.
