video_device_release_empty(9)

✨ video_device_release_empty ✨

okay bestie, welcome to the Kernel API Manual 💖 this one's a tiny little helper in video_device_release_empty(9) and honestly it's giving "short but iconic" 🎀

---

🌸 NAME 🌸

video_device_release_empty — the helper function you use to implement the video_device->release callback. that's it, that's the whole job, slay 💅

---

🦋 SYNOPSIS 🦋

void video_device_release_empty (struct video_device *vdev );

---

🍓 ARGUMENTS 🍓

• vdev — a pointer to struct video_device. yep, that's the one and only argument, no cap 🫶

---

💜 DESCRIPTION 💜

So like… this release function does nothing. literally nothing. it's an empty function doing empty-function things and it's thriving ✨

You should use it when the video_device is a static global struct. that's the vibe check it passes 🧚

NOTE: ngl, having a static video_device is a dubious construction at best 😭 so like, proceed with awareness, bestie 💀
