Subject: [Intel-gfx] [PATCH 05/36] Restore "drm/i915: drop engine_pin/unpin_breadcrumbs_irq"
Date: Mon, 1 Jun 2020 08:24:15 +0100 [thread overview]
Message-ID: <20200601072446.19548-5-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <20200601072446.19548-1-chris@chris-wilson.co.uk>
This was removed in commit 478ffad6d690 ("drm/i915: drop
engine_pin/unpin_breadcrumbs_irq") as the last user had been removed,
but now there is a promise of a new user in the next patch.
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
