Subject: [PATCH v3 15/20] drm/dp_dual_mode: Pass drm_device to drm_lspcon_(get|set)_mode()
Date: Mon, 19 Apr 2021 18:55:17 -0400	[thread overview]
Message-ID: <20210419225523.184856-16-lyude@redhat.com> (raw)
In-Reply-To: <20210419225523.184856-1-lyude@redhat.com>

So that we can start using drm_dbg_*() throughout the DRM DP helpers.
