From: Jean Pihet <[email protected]> It is not needed to iterate through all the clock domains of a power domain in order to allow or deny it to idle. This patch allows or denies only the first registered clock domain of a power domain, and so optimizes the latency of the low power code. The functions _cpuidle_allow_idle and _cpuidle_deny_idle are not used anymore and so are removed.
