2022-07-09drm/mipi-dsi: Make remove callback return voidUwe Kleine-König
All implementations return 0 and the return value of mipi_dsi_drv_remove() is ignored anyhow. So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour.

2020-07-01drm/panel: st7703: Assert reset prior to powering down the regulatorsOndrej Jirman
The reset pin is inverted, so if we don't assert reset, the actual gpio will be high and may keep driving the IO port of the panel.
