Subject: media: v4l: ioctl: Set bus_info in v4l_querycap() Author: Sakari Ailus <[email protected]> Date: Sat Jan 22 13:23:18 2022 +0000 The bus_info field is set by most drivers based on the type of the device bus as well as the name of the device. Do this in v4l_querycap() so drivers don't need to. This keeps compatibility with non-default and silly bus_info.
