Subject: cmd64x: set IDE_HFLAG_SERIALIZE explictly for CMD646
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6b5cde3629701258004b94cde75dd1089b556b02;p=linux-beck.git

cmd64x: set IDE_HFLAG_SERIALIZE explictly for CMD646

* Set IDE_HFLAG_SERIALIZE explictly for CMD646.

* Remove no longer needed ide_cmd646 chipset type (which has
  a nice side-effect of fixing handling of unexpected IRQs).
