Hi Krzysztof, I'm sorry for my unkonwing about the kernel patching process. And I'm sorry to let maintainers do extra work. Thank you for teaching me this. I will do this right in future patches. I did received a Acked-by tag from Conor in v4: Acked-by: Conor Dooley <conor.dooley@xxxxxxxxxxxxx> I note it here in case someone forgets this tag.
