---------------------------
What: old NCR53C9x driver
When: October 2007
Why: Replaced by the much better esp_scsi driver. Actual low-level
driver can ported over almost trivially.
Who: David Miller <davem@davemloft.net>
Christoph Hellwig <hch@lst.de>
---------------------------
What: Video4Linux API 1 ioctls and video_decoder.h from Video devices.
When: December 2006
Why: V4L1 AP1 was replaced by V4L2 API. during migration from 2.4 to 2.6
