DMA: shdma: Fix warnings due to improper casts and printk formats
Use the %zu and %pad printk specifiers to print size_t and dma_addr_t variables, and cast pointers to uintptr_t instead of unsigned int where applicable. This fixes warnings on platforms where pointers and/or dma_addr_t have a different size than int Cc: Guennadi Liakhovetski <g.liakhovetski+renesas@gmail.com> Cc: Vinod Koul <vinod.koul@intel.com> Cc: dmaengine@vger.kernel.org Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
