Subject: [PATCH 7/7] i2c: stm32f7: : use proper DMAENGINE API for termination
Date:   Wed, 23 Jun 2021 11:59:41 +0200
Message-Id: <20210623095942.3325-8-wsa+renesas@sang-engineering.com>

dmaengine_terminate_all() is deprecated in favor of explicitly saying if
it should be sync or async. Here, we want dmaengine_terminate_sync()
because there is no other synchronization code in the driver to handle
an async case.
