[PATCH 0/1] iio: convert to use new I2C API

[Wolfram Sang]

We are deprecating calls which return NULL in favor of new variants which
return an ERR_PTR.

Applied to the togreg branch of iio.git and pushed out as testing.

Note this has missed the coming merge window.  Hope that doesn't matter for your

No worries. If I can remove it in the cycle after the next, I am happy.

Thanks!
