To: bzolnier; +Cc: linux-ide
Move IDE_FTFLAG_{IN|OUT}_DATA flag handling out of tf_{read|load}() methods
into the only two functions where these flags actually need to be handled:
do_rw_taskfile() and ide_complete_cmd()...

This patch is atop of the latest pata-2.6 series...
Fixed reject after changing the preceding patch.
