Hi  Paul

Thanks for your reply.

because I can't use company email to send the patch upstream.
So BMC NPCM all drivers always  use gmail to send the patch.
It's the company mail security rule. I am sorry about that.
After the V3 version I changed to gmail.

Yes, so should i change u8 ,u16, u32 to standard `unsigned int` is
better than now?
Could you provide more information?

Best regards,
Jim
