| commit f3895311ef49171b58b5ea1f06942408c8685a1e
| Author: Lucas Stach <l.stach@pengutronix.de>
| Date:   Fri Jul 22 15:00:19 2016 +0200
|
|     state: only build circular backend if MTD is enabled
|
|     The circular backend depends on MTD symbols and is only useful
|     if MTD is present. Exclude it from the build if MTD is not enabled.
