From 03fc41afaa6549baa2dab7a84e1afaf5cadb5b18 Mon Sep 17 00:00:00 2001 From: Zhang Qilong Date: Fri, 6 Nov 2020 09:24:21 +0800 Subject: spi: mxs: fix reference leak in mxs_spi_probe pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to pm_runtime_put_noidle will result in reference leak in mxs_spi_probe, so we should fix it.
