Hello to all,

I apologize for this easily avoidable mistake. I'm about to post the v2 
series.

However, I write this message to affirm that Pavel's tests on this patch are 
still valid and confirmed because his copy *has* the right parameter that is 
REALTEK_USB_VENQT_WRITE.

It's all my fault. Pavel warned me that during the review and test he noticed 
that I had written REALTEK_USB_VENQT_READ and obviously my build was 
successful because it was a symbol known to the compiler.

Pavel successfully changed his local copy and I (independently) changed mine 
without thinking about rebuilding. I was absolutely certain it was the 
expected parameter (perhaps the function name - usb_control_msg_send () - 
played a part in leading me to this stupid mistake).

In summary, first I want to apologize for the noise, secondly I want to 
apologize to Pavel who is co-author and tester of this 3/3 of our series.

Regards,

Fabio
