Introduce sensor name in st_lsm6dsx_sensor_settings table. This is
a preliminary patch to add I3C support to st_lsm6dsx since i3c_device_id
data structure does not contain a name field
Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org>
---
changes since v2:
- use const char *name instead of const char name[32] in
st_lsm6dsx_settings
changes since v1:
- move sensor name in st_lsm6dsx_sensor_settings

Applied to the togreg branch of iio.git and pushed out as testing for
the autobuilders to play with it.
