From 5616ce7b780af6103d7724f119514a6eb7b05f66 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Wed, 2 Nov 2022 22:21:01 +0800 Subject: PM: domains: Drop genpd status manipulation for hibernate restore The genpd status manipulation for hibernate restore has really never worked as intended. For example, if the genpd->status was GENPD_STATE_ON, the parent domain's `sd_count` must have been increased, so it needs to be adjusted too. So drop this status manipulation.
