Subject: [Intel-gfx] [PATCH 3/4] drm/i915/guc: Clear pointers on free
Date: Mon, 21 Sep 2020 10:54:27 -0700 [thread overview]
Message-ID: <20200921175428.2914478-4-John.C.Harrison@Intel.com> (raw)
In-Reply-To: <20200921175428.2914478-1-John.C.Harrison@Intel.com>
From: John Harrison <John.C.Harrison@Intel.com>
Was hitting null pointers and similar issues when running various
module load/unload and inject failure type tests. So clear those
pointers down when the objects have been de-allocated.
Signed-off-by: John Harrison <John.C.Harrison@Intel.com>
