	)

Value:

  PBL_ALS_STATE_DEFINE(sym);                                                       \

  PBL_DEVICE_REGISTER(sym, &sym.als.dev)

Define an OPT3001.

Parameters

sym	Symbol of the instance; the sensor is sym.als.
_bus	I2C bus.
_addr	7-bit I2C address.
_scale	Lux calibration (const struct pbl_als_scale *), or nullptr.
...	Designated initializers of the remaining fields: always_on.
