[RC PATCH 19/19] ide: remove deprecated icside host driver
From: Bartlomiej Zolnierkiewicz
Date: Thu Feb 04 2016 - 08:47:59 EST
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_icside) has been available since
2007 and it supports all the hardware supported by the old
icside host driver. Also ARM rpc_defconfig has switched to use
libata PATA exclusively in 2007.
Remove the deprecated icside host driver.
