Subject: [PATCH 1/3] drm/encoder: Fix possible_clones documentation
Date: Fri, 13 Sep 2019 18:27:01 -0400	[thread overview]
Message-ID: <20190913222704.8241-2-lyude@redhat.com> (raw)
In-Reply-To: <20190913222704.8241-1-lyude@redhat.com>

We say that all of the bits in possible_clones must be set before
calling drm_encoder_init(). This isn't true though, since:

* The driver may not even have all of the encoder objects that could be
  used as clones initialized at that point
* possible_crtcs isn't used at all outside of userspace, so it's not
  actually needed to initialize it until drm_dev_register()

So, fix it.
