[PATCH] regulator: max14577: Fix invalid return value on DT parse success

[Krzysztof Kozlowski <k.kozlowski@samsung.com>]

This fixes bug introduced in 667a6b7a (regulator: max14577: Add missing
of_node_put). The DTS parsing function returned number of matched
regulators as success status which then was compared against 0 in probe.

Result was a probe fail after successful parsing the DTS:
max14577-regulator: probe of max14577-regulator failed with error 2
