Re: [PATCH v4 0/2] ASoC: Intel: Add Lenovo Yoga Book RT5677 support

Hi Maurizio,

I am glad to see my (a bit abandoned) work to have YB1-X9* support in
mainline be continued but please don't drop
my ownership for patches when using them. Use Co-developed-by: to
mention me as co-developer
and keep my Signed-off-by: tags.

For reference, my WiP v4 tree is here:
