Do you really need this change ? sn9c2028_read1 returns either a negative
error code, or the byte read from the sn9c2028 chip. This functions wait for
the sn9c2028 to return a read value of 2. I admit that the check in the for
vs the check in the error reporting is not chosen well, both should probably
be != 2. But checking for status < 0 is not good as this does not catch
a successful read from the chip not returning 2.
