Subject: [PATCH] hrtimer/treewide: Use hrtimer_sleeper_start_expires()
Git-commit: 9dd8813ed9f6e2bba75434abc6c8bb06c3d87fdc
Patch-mainline: v5.4-rc1
References: bsc#1149032

hrtimer_sleepers will gain a scheduling class dependent treatment on
PREEMPT_RT. Use the new hrtimer_sleeper_start_expires() function to make
that possible.
