Subject: [PATCH 5.4 299/411] rpmsg: qcom_smd: Fix returning 0 if irq_of_parse_and_map() fails

From: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

[ Upstream commit 59d6f72f6f9c92fec8757d9e29527da828e9281f ]

irq_of_parse_and_map() returns 0 on failure, so this should not be
passed further as error return code.

Fixes: 1a358d350664 ("rpmsg: qcom_smd: Fix irq_of_parse_and_map() return value")
