[PATCH v2 05/31] KVM: arm64: Switch to use hrtimer_setup()

From: Nam Cao
Date: Wed Feb 05 2025 - 05:40:12 EST


hrtimer_setup() takes the callback function pointer as argument and
initializes the timer completely.

Replace hrtimer_init() and the open coded initialization of
hrtimer::function with the new setup mechanism.
