Same as stable-rc/linux-4.9.y, this needs a backport of 93407472a21b ("fs: add
i_blocksize()")

>       1  drivers/dma/ep93xx_dma.c:1357:9: error: 'struct dma_device' has no member named 'device_synchronize'

The error was introudced by the backport of 98f9de366fcc ("dmaengine: ep93xx:
Don't drain the transfers in terminate_all()"), which requires the dmaengine
synchronize callback.

device_synchronize was introduced by b36f09c3c441 ("dmaengine: Add transfer
termination synchronization support") in linux-4.5. That is not a
bugfix but would
cleanly apply on top of 4.4 and has no dependencies or side-effects.

We can either revert 98f9de366fcc or backport b36f09c3c441.
