Subject: [PATCH] spi: stm32: fix pm_runtime_get_sync() error checking
Date: Wed, 9 Sep 2020 12:43:04 +0300
Message-ID: <20200909094304.GA420136@mwanda> (raw)

The pm_runtime_get_sync() can return either 0 or 1 on success but this
code treats 1 as a failure.

Fixes: db96bf976a4f ("spi: stm32: fixes suspend/resume management")
