From 3482e797ab688da6703fe18d8bad52f94199f4f2 Mon Sep 17 00:00:00 2001 From: Zhang Qilong Date: Tue, 3 Nov 2020 22:13:23 +0800 Subject: spi: tegra20-sflash: fix reference leak in tegra_sflash_resume pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to pm_runtime_put_noidle will result in reference leak in tegra_sflash_resume, so we should fix it.
