%zu is the dedicated type for size_t. %d only works on 32bit architectures where size_t is typedef'd to be unsigned int. (And then the signedness doesn't fit, but `gcc -Wformat` doesn't stumble over this. Also the size of dma_addr_t is architecture dependent and it should be printkd using %pad (and the value passed by reference). This prepares allowing this driver to be compiled on non-mips platforms.
