[RFC PATCH 11/19] ide: remove deprecated opti621 host driver

Show all headers | View raw

IDE subsystem has been deprecated since 2009 and the majority
(if not all) of Linux distributions have switched to use
libata for ATA support exclusively.

The replacement driver (pata_opti) has been available since
2006 and it supports all the hardware supported by the old
opti621 host driver.

Remove the deprecated opti621 host driver.
