|Maybe I should remove iio_device_claim_direct_mode() and release(),
there is actually nothing in the datasheet that block us from reading temp and raw
axis data with streaming enabled to the internal fifo.
We have a use-case for reading temperature data while streaming accelerometer data.

Could I just check for ||iio_buffer_enabled||() and skip the drdy and power_on/off in
||fxls8962af_get_temp() and ||fxls8962af_get_axis()||?
