From: Paul Mundt <lethal at linux-sh.org>

Leading up to the ->device_prep_slave_sg change in
185ecb5f4fd43911c35956d4cc7d94a1da30417f 'dmaengine: add context
parameter to prep_slave_sg and prep_dma_cyclic' a generic wrapper was
added in place to guard against the API change, though the fsi driver
wasn't updated in the process (presumably its dmaengine support hadn't
been merged yet at the time). This trivially switches over to the new
wrapper and gets it building again.

Nothing happened on ALSA ML.
So I forward this patch.
I added my Acked-by on it.
