Subject: [PATCH] spi: img-spfi: add missing pm_runtime_pu
Date: Tue, 2 Jun 2020 00:46:19 -0500 [thread overview]
Message-ID: <20200602054619.4352-1-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.
