Suspend and resume functions call spi_master_get() without matching
spi_master_put(). The extra references are unnecessary and cause
subsequent module unload attempts to fail, so drop the calls.

The call sequence spi_alloc_master/spi_register_master/spi_unregister_master is
complete; it reduces the device reference count to zero, which and results in
device memory being freed. The subsequent call to spi_master_put is unnecessary
and results in an access to free memory. Drop it.

Add a DMA engine driver for the TI EDMA controller. This driver
is implemented as a wrapper around the existing DaVinci private
DMA implementation. This approach allows for incremental conversion
of each peripheral driver to the DMA engine API. The EDMA driver

This series begins the conversion of the DaVinci private
EDMA API implementation to a DMA engine driver and
converts two of the three in-kernel users of the private
EDMA API to DMA engine.
The approach taken is similar to the recent OMAP DMA
Engine conversion. The EDMA DMA Engine driver is a

Better yet, remove these calls - they're completely redundant.
