Subject: [PATCH] drm: Add name for DRM_DP_DUAL_MODE_LSPCON
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Handle DRM_DP_DUAL_MODE_LSPCON in drm_dp_get_dual_mode_type_name(),
otherwise a call to that function can theoretically trigger a WARN.

Fixes: 056996b95686 ("drm: Helper for lspcon in drm_dp_dual_mode")
