Subject: [PATCH] media: stm32-dcmi: remove deprecated dmaengine_terminate_all()
Date:   Wed, 7 Oct 2020 18:05:52 +0200
Message-ID: <1602086752-8987-1-git-send-email-hugues.fruchet@st.com>
MIME-Version: 1.0
Content-Type: text/plain
Precedence: bulk

Replace dmaengine_terminate_all() by dmaengine_terminate_sync()
to ensure that all pending dma operations are really finished.
This is not ensured by dmaengine_terminate_all() and this API
is deprecated, so better to use the _sync() variant.
