[PATCH 08/15] dmaengine: dw: define counter variables as unsigned int

[Mans Rullgard]

From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>

The code is fixed to satisfy a compiler otherwise we have

drivers/dma/dw/core.c: In function âdwc_handle_cyclicâ:
drivers/dma/dw/core.c:568: warning: comparison between signed and unsigned
drivers/dma/dw/core.c: In function âdw_dma_taskletâ:
drivers/dma/dw/core.c:590: warning: comparison between signed and unsigned
drivers/dma/dw/core.c: In function âdw_dma_offâ:
drivers/dma/dw/core.c:1103: warning: comparison between signed and unsigned
drivers/dma/dw/core.c: In function âdw_dma_cyclic_freeâ:
drivers/dma/dw/core.c:1469: warning: comparison between signed and unsigned
drivers/dma/dw/core.c: In function âdw_dma_probeâ:
drivers/dma/dw/core.c:1574: warning: comparison between signed and unsigned

There is no functional change.
