Subject: [PATCH v3 4/7] ACPI / processor: remove cpu_index in acpi_processor_get_info()
Date: Mon, 11 May 2015 12:17:16 +0800	[thread overview]
Message-ID: <1431317839-4584-5-git-send-email-hanjun.guo@linaro.org> (raw)
In-Reply-To: <1431317839-4584-1-git-send-email-hanjun.guo@linaro.org>

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