Some platforms generate auto command error interrupt when it shouldn't, e.g. auto-cmd12 while in close-ended ffu sequence. I encounterd this issue while testing fwup on HP Chromebook x2, qualcomm based QC-7c, code name for board - strongbad. Instead of a quirk, hook the request function of the msm ops, so it'll disable auto-cmd12 while close-ended ffu is in progress.
