Subject: [PATCH v2 1/7] ACPI / processor: remove cpu_index in acpi_processor_get_info()
Date: Tue,  5 May 2015 10:46:32 +0800	[thread overview]
Message-ID: <1430793998-21631-2-git-send-email-hanjun.guo@linaro.org> (raw)
In-Reply-To: <1430793998-21631-1-git-send-email-hanjun.guo@linaro.org>

Just use pr->id instead of cpu_index to simplify the code.
