From 45c0cba753641e5d7c3207f04241bd0e7a021698 Mon Sep 17 00:00:00 2001 From: Zhang Qilong Date: Tue, 3 Nov 2020 22:09:47 +0800 Subject: [PATCH] spi: spi-ti-qspi: fix reference leak in ti_qspi_setup pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to pm_runtime_put_noidle will result in reference leak in ti_qspi_setup, so we should fix it.
