There is three users working on getting their code accepted in main
line. I have been trying to get my tda998x patches reviewed for some
time now, but not lately, because I have been busy with my other tasks.

The two others are Philipp Zabel and Arnaud Pouliquen, both in cc. Not
sure if they actually have some patches already queued for mainline.

Best regards,
Jyri
