With the patch, oldconfig prompts for it as (NEW) > and listnewconfig lists it. Generally drivers are unselected by default and cvs is no exception. What I think we could possibly do is to add to cvs Kconfig: default VIDEO_INTEL_IPU6 As the cvs driver is (at least right now) used with ipu6 driver only. That being said, there are probably dozens of configuration options you need to select to have a functional camera so doing this for cvs only won't make a lot of difference. I presume it was just a coincidence this happened on Arch. This is still a configuration option that make oldconfig will ask about so it won't be silently ignored as when MEDIA_HIDE_ANCILLARY_SUBDRV was selected. -- Kind regards, Sakari Ailus
