drivers/isdn/sc/event.c:49: warning: format '%d' expects type 'int', but argument 4 has type 'ulong'

drivers/isdn/sc/interrupt.c: In function 'interrupt_handler':
drivers/isdn/sc/interrupt.c:97: warning: format '%x' expects type 'unsigned int', but argument 4 has type 'long unsigned int'

drivers/isdn/sc/timer.c: In function 'check_reset':
