Subject: [PATCH] drm/i915/fence: Do not use TIMER_IRQSAFE
Date: Tue, 12 Feb 2019 17:28:57 +0100	[thread overview]
Message-ID: <20190212162857.20003-1-bigeasy@linutronix.de> (raw)

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.
