Sometimes I am confused about this review process.

The new code is same as previous code submitted.  The old code was accepted,
but then there are objections to the new code.

So if I change the new code, should I go back to correct the old code?

The ksz9477_i2c.c should be the same as ksz9477_i2c.c while ksz_i2c.h matches
ksz_spi.h.  The idea is ksz_i2c.h can be used by another switch driver like ksz####_i2c.c.
