gcc reports:
kernel/sched/rt.c:626:6: warning: no previous prototype for ‘sched_rt_bandwidth_account’
Let's declare it, and remove the declaration from the source file where it is called.
Fixes: faa5993736d9 ("sched/deadline: Prevent rt_time growth to infinity") Signed-off-by: Guenter Roeck <linux@roeck-us.net> --- Note: I know that checkpatch complains about this. I declared the function 'extern' to match other declarations in sched.h.
