Subject: [PATCH v9 03/15] ACPI/IORT: Rework iort_match_node_callback() return value handling
Date: Tue, 7 Mar 2017 20:39:58 +0800 [thread overview]
Message-ID: <1488890410-15503-4-git-send-email-guohanjun@huawei.com> (raw)
In-Reply-To: <1488890410-15503-1-git-send-email-guohanjun@huawei.com>
From: Hanjun Guo <hanjun.guo@linaro.org>
The return value handling in iort_match_node_callback() is
too convoluted; update the iort_match_node_callback() return
value handling to make code easier to read.
