Subject: [PATCH] drm/armada: Fix a potential double free in armada_drm_bind
Date: Sat, 16 Apr 2022 07:16:41 +0000	[thread overview]
Message-ID: <20220416071641.30386-1-linmq006@gmail.com> (raw)

priv is a managed resource allocated with devm_drm_dev_alloc(), so there
is no need to call kfree() explicitly or there will be a double
free.

Fixes: 90ad200b4cbc ("drm/armada: Use devm_drm_dev_alloc")
