Hi Laurent,

linux-next has failed to build with lager_defconfig and marzen_defconfig for a while,
with this error:

arch/arm/mach-shmobile/board-lager.c:35:41: fatal error: linux/platform_data/rcar-du.h: No such file or directory
 #include <linux/platform_data/rcar-du.h>

which is evidently the result of your patch

    drm: rcar-du: Remove platform data support
    
    All platforms now instantiate the DU through DT, platform data support
    isn't needed anymore.

that removes the header files. I assume some dependency wasn't tracked
right, since linux-next still has these.

$ git grep rcar_du_ arch/arm
arch/arm/mach-shmobile/board-lager.c:static struct rcar_du_encoder_data lager_du_encoders[] = {
arch/arm/mach-shmobile/board-lager.c:static const struct rcar_du_platform_data lager_du_pdata __initconst = {
arch/arm/mach-shmobile/board-marzen.c:static struct rcar_du_encoder_data du_encoders[] = {
arch/arm/mach-shmobile/board-marzen.c:static const struct rcar_du_platform_data du_pdata __initconst = {

Can we please fix this before the merge window? Should the platform
device registration just get removed from the two board files?
