Subject: [PATCH] spi: tegra20-slink: add missing pm_runtime_put
Date: Tue,  2 Jun 2020 00:26:02 -0500	[thread overview]
Message-ID: <20200602052602.91374-1-navid.emamdoost@gmail.com> (raw)

Call to pm_runtime_get_sync increments counter even in case of
failure leading to incorrect ref count.
Call pm_runtime_put if pm_runtime_get_sync fails.
