Subject: [PATCH v7 12/20] drm/nouveau: Remove bogus cleanup in nv50_mstm_add_connector()
Date: Thu, 10 Jan 2019 19:53:35 -0500	[thread overview]
Message-ID: <20190111005343.17443-13-lyude@redhat.com> (raw)
In-Reply-To: <20190111005343.17443-1-lyude@redhat.com>

Trying to destroy the connector using mstc->connector.funcs->destroy()
if connector initialization fails is wrong: there is no possible
codepath in nv50_mstc_new where nv50_mstm_add_connector() would return
<0 and mstc would be non-NULL.
