A very trivial comment inline. Feel free to ignore!

I don't care that much, but you could combine parameters on one line in
a few more places to reduced the code length a little.
e.g.
I'd be tempted to put the two lines above on one line or even

		ret = regmap_bulk_read(data->regmap, VEML6031X00_REG_ALS_L,
				       scan, 2 * sizeof(*scan));
