usb_release_dev(9)

💖 NAME 💖

okay so bestie, welcome to the usb_release_dev(9) page from the Kernel API Manual ✨ this icon is here to free a usb device structure when all users of it are finished. that’s the whole vibe: cleanup era, no cap 🧹💅

🌸 SYNOPSIS 🌸

void usb_release_dev (struct device *dev );

🎀 ARGUMENTS 🎀

• dev — device that's been disconnected

that’s the only argument, bestie — short and iconic 🫶

🦋 DESCRIPTION 🦋

so here’s the tea ☕: this function Will be called only by the device core when all users of this usb device are done. literally that’s it — the device core handles the timing, and this is the “everyone’s done, wrap it up” moment 🎬✨
