Subject: [PATCH v4 2/8] drm/nouveau: Enable polling even if we have runtime PM
Date: Wed,  1 Aug 2018 17:14:52 -0400	[thread overview]
Message-ID: <20180801211459.7731-3-lyude@redhat.com> (raw)
In-Reply-To: <20180801211459.7731-1-lyude@redhat.com>

Having runtime PM makes no difference on whether or not we want polling,
and it's now safe to just enable polling unconditionally in drm_load()
thanks to d61a5c106351 ("drm/nouveau: Fix deadlock on runtime suspend")
