Zhiyi Zhang (@zhiyi) commented about dlls/win32u/sysparams.c:
place_all_displays( displays );
- ret = user_driver->pChangeDisplaySettings( displays, hwnd, flags, lparam );
- if ((ret = user_driver->pChangeDisplaySettings( displays, hwnd, flags, lparam )) == E_NOTIMPL)
I think it would be better to have some comments noting the fallback to nulldrv. Same for later patches.
