Description:

[ Upstream commit 7e5705c635ecfccde559ebbbe1eaf05b5cc60529 ]

When building cpupower with clang, the following warning appears:

 utils/idle_monitor/hsw_ext_idle.c:42:16: warning: initializer overrides

 1 warning generated.

This appears to be a copy and paste or merge mistake because the name
and id fields both have PC9 in them, not PC2. Remove the second
assignment to fix the warning.
