Subject: i2c: I2C_MT65XX should depend on HAS_DMA
X-Git-Tag: firefly_0821_release~176^2~1434^2~3

i2c: I2C_MT65XX should depend on HAS_DMA

If NO_DMA=y:

    ERROR: "dma_unmap_single" [drivers/i2c/busses/i2c-mt65xx.ko] undefined!
    ERROR: "dma_mapping_error" [drivers/i2c/busses/i2c-mt65xx.ko] undefined!
    ERROR: "dma_map_single" [drivers/i2c/busses/i2c-mt65xx.ko] undefined!

Add a dependency on HAS_DMA to fix this.
