From ee5558a9084584015c8754ffd029ce14a5827fa8 Mon Sep 17 00:00:00 2001 From: Zhang Qilong Date: Mon, 2 Nov 2020 22:56:51 +0800 Subject: spi: img-spfi: fix reference leak in img_spfi_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 img_spfi_resume, so we should fix it.
