Re: [PATCH 04/11] iio: pressure-i2c: st: Simplify error checking in probe()

Hi Lee. This won't apply as this driver has already been cleaned up using devm_iio_device_alloc.

Guessing you are basing on an old tree?
Always use at least staging-next for IIO patches.

I think this one will hit mainline in next few days.
