Comment 5 for bug 184783

Gosh I'm very sorry,
I realized too late that in the last comment the output was successful just because there was no link_power_management_policy file in host0 (I do not understand why, but some recent kernel update mush have moved the host having link_power_management_policy from host0 host1 & host2 to host2, host3 & host4). Anyway I corrected one more the report and the but is still there, no way to set those attributes via sysfsutils!
(still, however, other tweaks are possible and are done without issues
(in devices/system/cpu/cpu0/cpufreq/scaling_governor
and module/snd_hda_intel/parameters/power_save )
