Subject[PATCH 4.4 001/131] mmc: pxamci: fix enum type confusion
Date
4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@arndb.de>

commit e60a582bcde01158a64ff948fb799f21f5d31a11 upstream.

clang points out several instances of mismatched types in this drivers,
all coming from a single declaration:

drivers/mmc/host/pxamci.c:193:15: error: implicit conversion from enumeration type 'enum dma_transfer_direction' to
different enumeration type 'enum dma_data_direction' [-Werror,-Wenum-conversion]
direction = DMA_DEV_TO_MEM;
~ ^~~~~~~~~~~~~~
drivers/mmc/host/pxamci.c:212:62: error: implicit conversion from enumeration type 'enum dma_data_direction' to
different enumeration type 'enum dma_transfer_direction' [-Werror,-Wenum-conversion]
tx = dmaengine_prep_slave_sg(chan, data->sg, host->dma_len, direction,

The behavior is correct, so this must be a simply typo from
dma_data_direction and dma_transfer_direction being similarly named
types with a similar purpose.
