2019-02-18media: soc_camera: Depend on BROKENSakari Ailus
This patch makes the SoC camera framework as well as effectively the few remaining sensor drivers depend on BROKEN, rendering it uncompileable without changes in Kconfig. The purpose is to leave the code around if someone wishes to convert the drivers to the modern day V4L2 sub-device framework without having to go to see development history in git.
