Hi Birger,

I noticed what looks like a typo in the newly added `ax88179_read_cmd()`:

```c
if (size == 2) {
u16 buf = 0;

ret = __ax88179_read_cmd(dev, cmd, value, index, size, &buf);
le16_to_cpus(&buf);
*((u16 *)data) = buf;
} else if (size == 2) {
u32 buf = 0;

ret = __ax88179_read_cmd(dev, cmd, value, index, size, &buf);
le32_to_cpus(&buf);
*((u32 *)data) = buf;
}
```

The second condition should presumably be:

```c
} else if (size == 4) {
```

The original implementation before this code was moved to `ax88179_lib.c`
also used `else if (4 == size)`.

As written, the `u32` branch is unreachable, so 4-byte reads fall through
to `__ax88179_read_cmd()` without the `le32_to_cpus()` conversion.
