Wolfram and Jonathan,

Writing a patch to fix the new warnings generated by my I2C patch is
simple enough, but I'd like some help coordinating getting both
patches landed. Should I wait for the I2C patch to land in "for-next"
before sending the IIO fix, or would it be preferred to send the IIO
fix right now so that both patches can be reviewed simultaneously?
