From 6a5f95b5a4f4ff29e4071bc5b95f8f3a2aef046b Mon Sep 17 00:00:00 2001 From: Fieah Lim Date: Tue, 11 Sep 2018 03:59:01 +0800 Subject: 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 [ rjw: Changelog cleanup ] Signed-off-by: Rafael J.
