+Subject: [PATCH 098/347] hrtimer: consolidate hrtimer_init() +
+ hrtimer_init_sleeper() calls
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.246-rt110.tar.xz
+
+hrtimer_init_sleeper() calls require a prior initialisation of the
+hrtimer object with hrtimer_init(). Lets make the initialisation of
+the hrtimer object part of hrtimer_init_sleeper(). To remain
+consistent consider init_on_stack as well.
+
+Beside adapting the hrtimer_init_sleeper[_on_stack]() functions, call
+sites need to be updated as well.
