Subject: [PATCH 5.4 193/244] IB/hfi1: Fix error return code in parse_platform_config()

From: Wang Wensheng <wangwensheng4@...wei.com>

[ Upstream commit 4c7d9c69adadfc31892c7e8e134deb3546552106 ]

Fix to return a negative error code from the error handling case instead
of 0, as done elsewhere in this function.

Fixes: 7724105686e7 ("IB/hfi1: add driver files")
