Greetings,

I see in several iio drivers supporting triggered buffer mode that read_raw
returns -EBUSY when buffered sampling is enabled. This additional logic
is implemented in read_raw using iio_buffer_enabled().
Since some drivers don't implement this I'm wondering wether this logic is
an IIO design requirement or if this is device / driver specific.

Regards,
Grégor.
