iio: light: veml6070: Fix resource leak in probe error path

Browse source

The driver calls i2c_new_dummy_device() to create a dummy device,
then calls i2c_smbus_write_byte(). If i2c_smbus_write_byte() fails and
returns, the cleanup via devm_add_action_or_reset() was never registered,
so the dummy device leaks.

Switch to devm_i2c_new_dummy_device() which registers cleanup atomically
with device creation, eliminating the error-path window.
