13a8c6c2a1 iio:humidity: drop assign iio_info.driver_module and iio_trigger_ops.owner
The equivalent of both of these are now done via macro magic when
the relevant register calls are made.  The actual structure
elements will shortly go away.

ffebe74b7c iio: humidity: hts221: avoid useless ODR reconfiguration
Configure sensor ODR just in hts221_write_raw() in order to avoid
to set device sample rate multiple times.

f6f58d9d93 iio: humidity: hts221: do not overwrite reserved data during power-down
GENMASK(6, 3) in CTRL_REG1 and GENMASK(6, 2) in CTRL_REG2 are marked
reserved. Do not changed the original value (not declared in the
datasheet) during power-down/suspend routines.

bd49302a73 iio: humidity: hts221: refactor write_with_mask code
Move bit-shift in hts221_write_with_mask() instead of coding
the shift depth in the configured value. That change will be necessary
to fix an issue in device power-down procedure.
Simplify hts221_avg_list table management
