Well,
a) the return value of ahd_write_seeprom() is never checked (the only caller
   is ahd_proc_write_seeprom(),
b) Linux error codes are negative,
c) ahd_write_seeprom() has 'retval' and 'error' for returning error values
   back to the caller (which doesn't care...)

So to sum it up, this change doesn't change anything here. But "fixing" the
list above would make a change.

HTH,
