  Hello,

I don't want to step anyone's work here, so I'm sending this RFC to the
devs involved in the original discussion. I read on Uwe Kleine-König's
patchset submission thread the necessity for an i2c helper to aid with the
migration to the new i2c_driver .probe_new callback. Following the
suggestions made there, I wrote this small patchset implementing the
suggested helper function and ported the bmp280 IIO i2c probe to the new
probe using that helper.

Thanks for your time!
Angel

For the entire series (please drop RFC in the next version)

I'm happy to pick up the next version but a question on 'route' in to the kernel.

I can do an immutable branch with just the new function call in it if
that is useful given I assume this is applicable across a bunch of subsystems?

I'd think I should provide the immutable branch with the new I2C API
call. Feels a bit more logical. Will that work for you as well?

Absolutely. That's even better - I didn't want to assign you work to do :)
