Subject: [PATCH] hrtimers: Make sure hrtimer_resolution is unsigned int

From: Borislav Petkov <bp@...e.de>

... in the !CONFIG_HIGH_RES_TIMERS case too. And thus fix warnings like
this one:

net/sched/sch_api.c: In function ‘psched_show’:
net/sched/sch_api.c:1891:6: warning: format ‘%x’ expects argument of type ‘unsigned int’, but argument 6 has type ‘long int’ [-Wformat=]
      (u32)NSEC_PER_SEC / hrtimer_resolution);
