tools/power/x86/intel-speed-select: Change path for caching topology info (b1d12cef) · Commits · 戴 / test

We want to cache the topology info to a file, which is not preserved across boot cycle. The current storage in /tmp is getting preserved. So change the path from /tmp/isst_cpu_topology.dat to /var/run/isst_cpu_topology.dat. Signed-off-by:
