[PATCH v2 08/10] iio: light: veml6030: power off device in probe error paths

[Javier Carrasco <javier.carrasco.cruz@gmail.com>]

Move devm_add_action_or_reset() with a device shut down action above the
hardware initialization function to ensure that any error path after
powering on the device leads to a power off.

The power off action is carried out by setting the VEML6030_ALS_SD bit
of the VEML6030_REG_ALS_CONF, which is harmless in error paths were the
device is already off. On the other hand, making use of the registered
action in all error paths makes them more homogeneous by avoiding
special action depending on the current power state of the device.
