Indeed, relying on addr being not 0 cannot work because some device have
their register to set odr at address 0. As a matter of fact, if the odr
can be set, then there is a mask.

Hi Lary,
Which sensor has ODR in the register at address 0?
I see it's a few of the magnetometers from a quick grep, but please state
it in the cover letter. Also please add a suitable Fixes tag
as we will want this backported if appropriate.
Thanks,
Jonathan

Oh, sorry, just saw your answer. Ok I can list such sensors.
Please tell me what I should do about Fixes tag. That's the first time I send a patch I'm not sure What I should put in it.
Is it :
Fixes: 4358be137952 (MAINTAINERS: Add Syed Nayyar Waris to ACCES 104-QUAD-8 driver)
? Thank you.

Applied to the fixes-togreg branch of iio.git and marked for
stable.
Thanks,
