You can't possibly understand what that'll print. First of all, VEN_ID_H
and VEN_ID_L should be ORed together. Second, the user will see the same
message four times in a row, with different values, but see that driver
claims that all four values refer to the device id. What this should do,
is at least combine all four messages into a single one of the format:

dev_(dbg|info)(&i2c->dev, "SMSCxxx devid: %02x rev: %02x venid: %02x\n",
	devid, rev, (venid_h << 8) | venid_l);

or something similar.

Yes, I agree that the formatting here should also be improved - as I
said in one of my earlier mails if any of these things are fixed things
that should never change the driver should instead verify the value
rather than log it.
