From: Lukasz Krakowiak Date: Wed, 3 Apr 2019 10:32:54 +0000 (+0200) Subject: test/power: remove prefix ACPI X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c7ec1f26fd6e6e644121d221df8d55288776bbc0;p=dpdk.git test/power: remove prefix ACPI This patch removes prefix _acpi from power UT function/test names, and renames file test_power_acpi_cpufreq.c -> app/test/test_power_cpufreq.c.
