Given we now have iio_device_claim_direct_scoped() to perform automatic releasing of direct mode at exit from the scope that follows it, this can be used in conjunction with guard(mutex) etc remove a lot of special case handling. Note that in this particular example code, there is no real reason you can't read channels via sysfs at the same time as filling the software buffer. To make it look more like a real driver constrain raw and processed channel reads from occurring whilst the buffer is in use.
