Sorry about missing that, I only noticed this warning recently and didn't
get around to submit a patch.

Thanks a lot guys for fixing this.

This MIPI DSIM driver is affectively a dead code in the mainline now, once
Exynos become a dt-only platform. I guess it can be deleted for 3.14, once
S5P gets converted to the device tree. The new driver using CDF is basically
a complete rewrite. Or device tree support should be added to that driver,
but I believe it doesn't make sense without CDF.
