cpuidle: Remove unnecessary wrapper cpuidle_get_last_residency()
cpuidle_get_last_residency() is just a wrapper for retrieving the last_residency member of struct cpuidle_device. It's also weirdly the only wrapper function for accessing cpuidle_* struct member (by my best guess is it could be a leftover from v2.x). Anyhow, since the only two users (the ladder and menu governors) can access dev->last_residency directly, and it's more intuitive to do it that way, let's just get rid of the wrapper. This patch tidies up CPU idle code a bit without functional changes. Signed-off-by: Fieah Lim <kw@fieahl.im> [ rjw: Changelog cleanup ] Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
