[PATCH 3/9] ide: add ->tf_load and ->tf_read methods

[Bartlomiej Zolnierkiewicz]

* Add ->tf_load and ->tf_read methods to ide_hwif_t and set the default
  methods in default_hwif_transport().

* Use ->tf_{load,read} instead o calling ide_tf_{load,read}() directly.

* Make ide_tf_{load,read}() static.

There should be no functional changes caused by this patch.

in short-term not much besides a nice optimization

in long-term it should enable us to remove ->IN*/OUT* methods completely

[PATCH 4/9] ide-cris: add ->tf_{load,read} methods

[Bartlomiej Zolnierkiewicz]

Add ->tf_{load,read} methods so cris_ide_{outb,outw,inb,inw}()
can be used directly.

There should be no functional changes caused by this patch.

[PATCH 5/9] ide-h8300: add ->tf_{load,read} methods

[PATCH 9/9] ide: remove ->INW and ->OUTW methods

[Bartlomiej Zolnierkiewicz]

* Remove no longer used ->INW and ->OUTW methods.

While at it:

* scc_pata.c: scc_ide_{out,in}w() is called only in scc_tf_{load,read}()
  so inline it there.
