ab32b2c363 media: stm32-dcmi: remove deprecated dmaengine_terminate_all()
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.

7519296da4 media: i2c: ov2680: simplify getting state container
The pointer to 'struct v4l2_subdev' is stored in drvdata via
v4l2_i2c_subdev_init() so there is no point of a dance like:

    struct i2c_client *client = to_i2c_client(struct device *dev)
    struct v4l2_subdev *sd = i2c_get_clientdata(client);

This allows to remove local variable 'client' and few pointer
dereferences.
