Subject: [PATCH v3 9/9] drm/rockchip: cdn-dp: Don't unregister audio dev when unbinding
Date: Wed, 5 Apr 2017 16:29:27 +0800 [thread overview]
Message-ID: <1491380967-28570-10-git-send-email-jeffy.chen@rock-chips.com> (raw)
In-Reply-To: <1491380967-28570-1-git-send-email-jeffy.chen@rock-chips.com>
After snd_soc_unregister_codec, the dai link would remain bound to
the invalid codec. That would cause crashes after unbind dp driver.
Let's unregister audio codec when removing dp driver to prevent that.
