Hi,

	 I checked and find that iio device name is usually named to be with underline if it has more than one word, so I assigned to be " linear_accel_3d".
 I think the device property node named to be "in_linear_accel_x_raw" is better than " in_linearaccel_x_raw" Just follow the former coding style.
"linearaccel" is only a name which specify IIO type [IIO_LINEAR_ACCEL]
I name [IIO_LINEAR_ACCEL] to be "linearaccel" just follow the history code style in " iio_chan_type_name_spec[]" which do not have any underline.

I think this would be in_linearaccel_x_raw, etc.?

linearaccel vs. linear_accel is a matter of taste, I have no preference;
nevertheless, the documentation should match what IIO outputs

We use underscores as the field separator in the channel name. Having a
underscore as part of a field adds ambiguity and makes it a lot harder
to machine parse it. It's already complicated enough as it is. We should
avoid adding types with underscores in them.
