Subject: [PATCH v7 01/13] drivers: base: cacheinfo: move cache_setup_of_node()
Date: Wed, 28 Feb 2018 16:06:07 -0600 [thread overview]
Message-ID: <20180228220619.6992-2-jeremy.linton@arm.com> (raw)
In-Reply-To: <20180228220619.6992-1-jeremy.linton@arm.com>
In preparation for the next patch, and to aid in
review of that patch, lets move cache_setup_of_node
further down in the module without any changes.
