v4l2_device_...subdev_nodes(9)

v4l2_device_...subdev_nodes(9) 💅

okay so this is the Kernel API Manual page for v4l2_device_...subdev_nodes(9), and bestie, it is short and sweet and very “read-only mode only” ✨

🎀 NAME 🎀

• v4l2_device_register_ro_subdev_nodes — registers subdevices device nodes in read-only mode. that’s the whole assignment: subdevices device nodes, but make it read-only, periodt 💅

🌸 SYNOPSIS 🌸

int v4l2_device_register_ro_subdev_nodes (struct v4l2_device *v4l2_dev
);

🦋 ARGUMENTS 🦋

• v4l2_dev — pointer to struct v4l2_device. she’s a pointer, no cap 🫶

💖 DESCRIPTION 💖

okay so internally this one calls __v4l2_device_register_subdev_nodes. literally that’s the move. if you want the full tea, see its documentation for more details ✨
