I was surprised too, and I compiled it twice and installed on both Ubuntu 16.04 and 16.10. I would guess it is config too. On 4.9, it was using Ubuntu default.

Re: [PATCH v2 0/6] Move dell-led to drivers/platform/x86
Hi everyone, It has been almost a month since I posted v2, so I hope sending a reminder is okay. Jaroslav, Takashi, could you please ack this patch series from the sound subsystem perspective? Patches 2-4 touch it. Anthony, have you and your team perhaps had a chance to test this patch series on actual hardware? Thanks, -- Best regards, Michał Kępień
