dmaengine: coh901318: fix pointer cast warnings
On some systems, pointer can be large than unsigned int, triggering warning pointer-to-int-cast on conversion. drivers/dma/coh901318.c: In function 'coh901318_filter_id': drivers/dma/coh901318.c:1769:23: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] unsigned int ch_nr = (unsigned int) chan_id; Also, converting an iomem pointer for print leads to warn on some system which can be avoided with %p specfier drivers/dma/coh901318.c: In function 'coh901318_probe': drivers/dma/coh901318.c:2748:3: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] (u32) base->virtbase); Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
