Hi Laurent, Thank you for the fix.

I'm afraid I may not be able to test it as I do not have the hardware. I have copied Chris P if he can help out. I have tested DRIF driver on a H3/M3 Salvator-X/S with a add-on board from Maxim having two MAX2175 tuners (MAX2175 evaluation kit). This add-on board was a prototype at that time. Hence, the DT updates were maintained internally. Thanks, Ramesh > I also haven't dug up my MAX9286 development kit to test 5/5.
