The change to %pad is done in order to use a consistent output for the dma_addr_t, which had a leading "0x" in two cases but not in the first one. printk interprets %pad as a pointer to a dma_addr_t and prints the address, not the pointer to it, see Documentation/printk-formats.txt, which lets you avoid the type cast as well as the 0x.
