Subject: [PATCH v8 01/13] drivers: base: cacheinfo: move cache_setup_of_node()
Date: Wed, 25 Apr 2018 18:31:09 -0500	[thread overview]
Message-ID: <20180425233121.13270-2-jeremy.linton@arm.com> (raw)
In-Reply-To: <20180425233121.13270-1-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.
