If anyone has any objections, please let me know. ------------------ From: Nícolas F. R. A. Prado [ Upstream commit c8048dd0b07df68724805254b9e994d99e9a7af4 ] The mtk_dp driver registers a phy device which is handled by the phy_mtk_dp driver and assumes that the phy probe will complete synchronously, proceeding to make use of functionality exposed by that driver right away. This assumption however is false when the phy driver is built as a module, causing the mtk_dp driver to fail probe in this case. Add the phy_mtk_dp module as a pre-dependency to the mtk_dp module to ensure the phy module has been loaded before the dp, so that the phy probe happens synchrounously and the mtk_dp driver can probe successfully even with the phy driver built as a module.
