[PATCH 2/2] cpuidle: Initialize power_usage for all C-states

[Thomas Schlichter]

By now, only the power_usage values of currently available C-states are
initialized in the function set_power_states(). But if the number of C-states
increases later (e.g. when using acpi_idle and unplugging the AC power from the
laptop) the power_usage values of the new C-states stay uninitialized.

Fix this by initializing all CPUIDLE_STATE_MAX C-stages in the first place.
