The support for 36-bit addresses originally came with an incorrect
printk format for dma addresses. Felipe changed the format string it
while applying, but the result was still incorrect, since we now have
to pass a pointer to the address instead of the integer value:

drivers/usb/mtu3/mtu3_qmu.c: In function 'mtu3_prepare_tx_gpd':
drivers/usb/mtu3/mtu3_qmu.c:261:25: error: format '%p' expects argument of type 'void *', but argument 7 has type 'dma_addr_t {aka unsigned int}' [-Werror=format=]
drivers/usb/mtu3/mtu3_qmu.c: In function 'mtu3_prepare_rx_gpd':
drivers/usb/mtu3/mtu3_qmu.c:300:25: error: format '%p' expects argument of type 'void *', but argument 7 has type 'dma_addr_t {aka unsigned int}' [-Werror=format=]

This fixes the printk argument accordingly.

oh, so it wants a pointer afterall :-)

sorry.
