From: Bartlomiej Zolnierkiewicz <bzolnier@...il.com>
To: linux-ide@...r.kernel.org
Cc: linux-kernel@...r.kernel.org
Subject: [PATCH 6/6] ide: remove ->INS{W,L} and ->OUTS{W,L} methods
* Use ins{w,l}()/outs{w,l}() and __ide_mm_ins{w,l}()/__ide_mm_outs{w,l}()
directly in ata_{in,out}put_data() (by using IDE_HFLAG_MMIO host flag to
decide which I/O ops are required).
* Remove no longer needed ->INS{W,L} and ->OUTS{W,L} methods (ide-h8300,
au1xxx-ide and scc_pata implement their own ->{in,out}put_data methods).
There should be no functional changes caused by this patch.
