Subject: [PATCH v10 08/15] memory: tegra20-emc: wait_for_completion_timeout() doesn't return error
Date: Mon, 12 Aug 2019 00:00:36 +0300
Message-ID: <20190811210043.20122-9-digetx@gmail.com> (raw)
In-Reply-To: <20190811210043.20122-1-digetx@gmail.com>

The "interruptible" variant may error out, the "uninterruptible" not.
