2023-04-18drm/panel: novatek-nt35950: Only unregister DSI1 if it existsKonrad Dybcio
Commit 5dd45b66742a ("drm/panel: novatek-nt35950: Improve error handling") introduced logic to unregister DSI1 on any sort of probe failure, as that's not done automatically by kernel APIs. It did not however account for cases where only one DSI host is used. Fix that.

2023-04-17drm/panel: novatek-nt35950: Improve error handlingKonrad Dybcio
In a very peculiar case when probing and registering with the secondary DSI host succeeds, but the OF backlight or DSI attachment fails, the primary DSI device is automatically cleaned up, but the secondary one is not, leading to -EEXIST when the driver core tries to handle -EPROBE_DEFER. Unregister the DSI1 device manually on failure to prevent that.

2023-01-11drm/panel-novatek-nt35950: Drop custom DSI write macroJavier Martinez Canillas
There is a macro for this already in the <drm/drm_mipi_dsi.h> header, use that instead and delete the custom DSI write macro defined in the driver.

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.
