H A Dalarmtimer-suspend.cdiff 61171d0407b537eff299aea2388773b6c760e6eb Wed May 13 17:13:05 CDT 2015 John Stultz <john.stultz@linaro.org> kselftests: timers: Check _ALARM clockids are supported before suspending

It was reported that the alarmtimer-suspend test hangs on older
systems that don't support _ALARM clockids.

This is due to the fact that we don't check if the timer_create
fails, and thus when we suspend, the system will not programatically
resume.

Fix this by checking the timer_create call for errors.
