Subject: [RFC PATCH 17/19] ide: remove deprecated triflex host driver
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_triflex) has been available since
2006 and it supports all the hardware supported by the old
triflex host driver.
Remove the deprecated triflex host driver.
