  CC [M]  drivers/staging/tidspbridge/rmgr/drv_interface.o
drivers/staging/tidspbridge/rmgr/drv_interface.c: In function 'bridge_mmap':
drivers/staging/tidspbridge/rmgr/drv_interface.c:275:2: warning: format '%lx' expects type 'long unsigned int', but argument 9 has type 'pgprot_t'

This patch fixes that warning message.
