Subject: [PATCH] spi: Add missing pm_runtime_put_noidle() after failed get
Git-commit: 7e48e23a1f4a50f93ac1073f1326e0a73829b631
Patch-mainline: v4.18-rc1
References: bsc#1111666

If pm_runtime_get_sync() fails we should call pm_runtime_put_noidle().
This is probably not a critical fix as we should only hit this when
things are broken elsewhere.
