The i2c core driver will turn the platform device ID to busnum
When using platfrom device ID as -1, it means dynamically assigned
the busnum. When writing code, we need to make sure the busnum,
and call i2c_register_board_info(int busnum, ...) to register device
if using -1, we do not know the value of busnum
In order to solve this issue, set the platform device ID as a fix number
Here using 0 to match the busnum used in i2c_regsiter_board_info()

can you check when this append for the first time to schedule a patch for stable too
OK. I will resend it and add linux stable into the cc list.
no this not how it work
I ask you to check which patch add the regression and then when this is
applied in the kernel we will request greg to apply it too to the stable
The code is using id = -1 appear 4 years ago. And after dig, I don't
find which patch cause this the regression.
so use git bisect to find the commit responsible
Thanks for your information.
Finally, I found the following commit add this:
3267c077e589bc146a0b45e220fcefafbf83fb80
