Ok, I'll do that.

There are two rds.h, related to V4L:
./include/linux/rds.h
./include/media/rds.h

One of them is at the public api:

include/linux/Kbuild:header-y += rds.h

Btw, that's weird:

$ git grep RDS_CMD_OPEN
drivers/media/video/saa6588.c:    case RDS_CMD_OPEN:
include/media/rds.h:#define RDS_CMD_OPEN  _IOW('R',1,int)

as saa6588 is a subdev.

IMO, we should remove or rename the internal header first.

There are also some issues there related to videodev2 stuff.

I prefer to apply the path as-is (just removing the ovcamchip.h) and,
on some later cleanup, check and fix the remaining stuff.

Thanks!

Not sure about that. I don't see any good reason to remove dabusb driver, as
nobody reported that it is broken.
