Since the MIPI-DSI interface is stopped at that\npoint, rzg2l_mipi_dsi_host_transfer() triggers the kernel panic.\n\nFix by moving rzg2l_mipi_dsi_stop() to new callback function\nrzg2l_mipi_dsi_atomic_post_disable().\n\nWith this change we now have the correct power-down/stop sequence:\n\n  systemd-shutdown[1]: Rebooting.\n  rzg2l-mipi-dsi 10850000.dsi: rzg2l_mipi_dsi_atomic_disable(): entry\n  ili9881c-dsi 10850000.dsi.0: ili9881c_unprepare(): entry\n  rzg2l-mipi-dsi 10850000.dsi: rzg2l_mipi_dsi_atomic_post_disable(): entry\n  reboot: Restarting system"
