From ca323b2c61ec321eb9f2179a405b9c34cdb4f553 Mon Sep 17 00:00:00 2001 From: Zhang Qilong Date: Tue, 1 Jun 2021 22:51:18 +0800 Subject: [PATCH] crypto: omap-sham - Fix PM reference leak in omap sham ops 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.
