Subject: [PATCH] rj54n1cb0c: remove compiler warning

From: Márton Németh <nm127@freemail.hu>

Remove the following compiler warning: 'dummy' is used uninitialized in this function.
Although the result in the dummy variable is not used the program flow in
soc_camera_limit_side() depends on the value in dummy. The program flow is better
to be deterministic.
