vio_find_node(9)

okay so bestie, welcome to the vio_find_node(9) page from the Kernel API Manual — this is the little lookup baddie for virtual devices, and yes she is iconic. 💅✨

🎀 NAME 🎀

vio_find_node — find an already-registered vio_dev. That's the assignment, no cap. 👑

✨ SYNOPSIS ✨

struct vio_dev * vio_find_node (struct device_node *vnode );

💅 ARGUMENTS 💅

• vnode — the device_node of the virtual device we're looking for. That's your target, bestie. 🎯🦋

🦋 DESCRIPTION 🦋

Heads up, because this part matters: it takes a reference to the embedded struct device, and that reference needs to be dropped after use. Not me reminding you to clean up after yourself — okay, it literally is me reminding you. 😭🧚
