[PATCH v3 3/5] iio: light: al3320a: Fix an error handling path in al3320a_probe()

[David Heidelberg via B4 Relay]

From: David Heidelberg <david@xxxxxxx>

If regmap_write() fails in al3320a_init(), al3320a_set_pwr_off is
not called.

In order to avoid such a situation, move the devm_add_action_or_reset()
which calls al3320a_set_pwr_off right after a successful
al3320a_set_pwr_on.
