From aa57e77b3d28f0df07149d88c47bc0f3aa77330b Mon Sep 17 00:00:00 2001 From: Zhang Qilong Date: Mon, 23 Nov 2020 18:18:27 +0800 Subject: HSI: Fix PM usage counter unbalance in ssi_hw_init pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to putting operation will result in reference leak here. We fix it by replacing it with pm_runtime_resume_and_get to keep usage counter balanced.
