lkdtm/bugs: fix build error in lkdtm_EXHAUST_STACK
lkdtm/bugs.c:94:2: error: format '%d' expects argument of type 'int', but argument 2 has type 'long unsigned int' [-Werror=format=]
pr_info("Calling function with %d frame size to depth %d ...\n",
^
THREAD_SIZE is defined as a unsigned long, cast CONFIG_FRAME_WARN to
unsigned long as well.
