Subject: tools/power turbostat: call __cpuid() instead of __get_cpuid()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=5aea2f7f645b27635b856311dee5b775d277c686;p=openwrt%2Fstaging%2Fblogic.git

tools/power turbostat: call __cpuid() instead of __get_cpuid()

turbostat already checks whether calling each cpuid leavf is legal,
and it doesn't look at the function return value,
so call the simpler gcc intrinsic __cpuid() instead of __get_cpuid().

syntax only, no functional change
