argh. Please just delete this version numbering. It's a sure-fire way of
maximising patch conflicts.

It's 1.10 in Bart's tree.

The code in Bart's tree has

static struct hpt_info hpt374 __devinitdata = {
.chip_type = HPT374,
.max_ultra = HPT374_ALLOW_ATA133_6 ? 6 : 5,
.dpll_clk = 48,
.settings = hpt37x_settings
};

I can handle the renaming, but note that Bart's tree has different values
as well.
