Subject: [PATCH v2] regulator: max14577: Fix invalid return value on DT parse
 success
Date: Fri, 21 Feb 2014 13:12:38 +0100
Message-id: <1392984758-10127-1-git-send-email-k.kozlowski@samsung.com>
Sender: linux-kernel-owner@vger.kernel.org

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
