Subject: [PATCH] drm/i915/fence: Do not use TIMER_IRQSAFE
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.0/older/patches-5.0.7-rt5.tar.xz
The timer is initialized with TIMER_IRQSAFE flag. It does look like the
timer callback requires this flag at all. Its sole purpose is to ensure
synchronisation in the workqueue code.
Remove TIMER_IRQSAFE flag because it is not required.
