However, drivers (often in trigger handlers) need to access it to iterate over the enabled channels for example (there are other reasons). Hence, a couple of new accessors are being added: * iio_for_each_active_channel() - Iterates over the active channels; * iio_get_masklength() - Get length of the channels mask. The goal of these new accessors is to annotate 'masklength' as private as soon as all drivers accessing it are converted to use the new helpers.
