i2c: xgene-slimpro: dma_mapping_error() doesn't return an error code
The dma_mapping_error() function returns true if there is an error, it doesn't return an error code. We should return -ENOMEM. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Reviewed-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de> Cc: stable@kernel.org
