cpuidle accounts the idle time for the C-state it was trying to enter and not to the actual state that the driver eventually entered. The driver may select a different state than the one chosen by cpuidle due to constraints like bus-mastering, etc. Change the time acounting code to look at the dev->last_state after returning from target_state->enter(). Driver can modify dev->last_state internally, inside the enter routine to reflect the actual C-state entered.
