[PATCH 3/3] ARM: shmobile: r8a7790: Constify platform data and resources

Tue Aug 27 21:39:32 EDT 2013
From: Laurent Pinchart <laurent.pinchart+renesas at ideasonboard.com>
Platform data and resources for core devices are kmemdup()ed when the
corresponding devices are registered and can thus be declared as const.
Do so.
