You forgot to mention the missing comma that caused a build failure...
I added the missing RSVD(4) when applying v2 and noticed that it failed
to compile but assumed that I had messed when amending the patch (and
fixed it up).
End result is here:

I'm sorry for the inconvenience.
Do I need to upload the v4 version to fix this commit message error?

I apologize for the automated disclaimer.
It is forced by our corporate mail server whenever sending emails externally.
Due to internal policies, we are required to use the company email address to submit the driver.
However, to avoid this footer issue,
is it acceptable if I use my personal email (wojackbb@gmail.com) to reply to the community from now on?
I can CC my personal email on the patches so I can jump into the thread using that address.
