dmaengine: dw: define counter variables as unsigned int
The code is fixed to satisfy a compiler otherwise we have drivers/dma/dw/core.c: In function ‘dwc_handle_cyclic’: drivers/dma/dw/core.c:568: warning: comparison between signed and unsigned drivers/dma/dw/core.c: In function ‘dw_dma_tasklet’: drivers/dma/dw/core.c:590: warning: comparison between signed and unsigned drivers/dma/dw/core.c: In function ‘dw_dma_off’: drivers/dma/dw/core.c:1103: warning: comparison between signed and unsigned drivers/dma/dw/core.c: In function ‘dw_dma_cyclic_free’: drivers/dma/dw/core.c:1469: warning: comparison between signed and unsigned drivers/dma/dw/core.c: In function ‘dw_dma_probe’: drivers/dma/dw/core.c:1574: warning: comparison between signed and unsigned There is no functional change.
