I think I will already merge this patch into the pdx86 tree:

https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/

While we are waiting for the rest of the series to get hashed out.

But as already pointed out by Trilok Soni your From: and Signed-off-by
email addresses don't match.

I can fix up the From to match the Signed-off-by while I apply this,
but before I do that I wanted to check with you that setting both
to "Jarrett Schultz <jaschultz@...rosoft.com>" is the right thing to do ?

Regards,

Hans
