drm: sun4i: print DMA address correctly
The newly added sun4i drm driver prints a dma address using the %x format string, which cannot work when dma_addr_t is 64 bit, and gcc warns about this configuration: drm/sun4i/sun4i_backend.c: In function 'sun4i_backend_update_layer_buffer': drm/sun4i/sun4i_backend.c:193:84: error: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'dma_addr_t {aka long long unsigned int}' [-Werror=format=] DRM_DEBUG_DRIVER("Using GEM @ 0x%x\n", gem->paddr); drm/sun4i/sun4i_backend.c:201:84: error: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'dma_addr_t {aka long long unsigned int}' [-Werror=format=] DRM_DEBUG_DRIVER("Setting buffer address to 0x%x\n", paddr); This changes the code to use the explicit %pad format string, which always prints the right length.
