Adriana, please put fixes at the start of such a series. It didn't matter here as the two changes were non overlapping but they take different paths so if there is overlap I need to get the fix out ASAP and then the improvements such as patch 1 can follow slower. Anyhow, applied to the fixes-togreg branch of iio.git (probably to go upstream post the merge window now).
