Subject: [PATCH v2 08/15] dmaengine: dw: define counter variables as unsigned int
Date: Mon, 22 Feb 2016 18:03:43 +0200	[thread overview]
Message-ID: <1456157030-54677-9-git-send-email-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <1456157030-54677-1-git-send-email-andriy.shevchenko@linux.intel.com>

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.
