From 7e48e23a1f4a50f93ac1073f1326e0a73829b631 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Fri, 18 May 2018 10:30:07 -0700 Subject: [PATCH] spi: Add missing pm_runtime_put_noidle() after failed get 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.
