Subject: [PATCH 1/3] misc: sram: Split sram data structures into local header
Date: Thu, 12 Jan 2017 14:52:18 -0600 [thread overview]
Message-ID: <20170112205220.26325-2-d-gerlach@ti.com> (raw)
In-Reply-To: <20170112205220.26325-1-d-gerlach@ti.com>
In preparation of a coming file split of the sram driver, move the
common data structures into a local header file that can be shared
between files related to the sram driver.
Signed-off-by: Dave Gerlach <d-gerlach@ti.com>
