.. there is an instance of it that looks like a "true positive", but it only
affects sdhc transfers that are not a multiple of 4 bytes, which I don't think
happens. (sd card blocks are always 512 bytes) I can fix this in our
asf4 repo but that would mean this should be deferred until after #3384 is
merged, since that also touches asf4 very invasively by adding a whole new
chip family.
