The function omap_usb2_set_comparator may return -ENODEV.
Use a signed variable to store and check so that the value
is not wrongly interpreted as a large positive number.
While at it lets use the err variable to do the same.

While at that can you just change the above to use IS_ERR?
IS_ERR() operates on pointers, not on integers. You probably meant:
if (err < 0)
