Why are you resending this less then 24 hours after the initial submission ?

Never mind, I see you added a missing Cc: platform-driver-x86@vger.kernel.org
which is good.

Next time please add a little note to the resend explaining why you
are resending it though.

Hi Hans,

Actually, my first patch was posted back on Feb 8, 2023.
On April 4, I resent the patch without RESEND tag, thus the new patch in less than 24h.

Apologies if I did something wrong.

Thanks,
-Khalil

Thank you for your patch, I've applied this patch to my review-hans 
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans

Note it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.

Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.

Regards,

Hans
