I think you have all necessary acks. I can take the DTS patch (5/5) although probably for next merge window as I just sent one. Best regards, Krzysztof

There was one patch 3/5 https://lkml.org/lkml/2019/6/5/215 which was waiting ACK or I missed the email somehow. Regards, Lukasz > > Best regards, > Krzysztof > >

When I was in vacation, your patches are removed on my email account because of the email expiration. So, I replied with my Ack through gmail account on mobile phone. But, there are some problem. My reply didn't arrive the mailing list. I have no any way to reply about this at company. After leaving one's office, I'll reply with Ack again at home. > > Regards, > Lukasz > >> >> Best regards, >> Krzysztof >> >> > >
