💖 v4l2_m2m_release(9) 💖

okay so welcome to the Kernel API Manual, bestie — this one's short but she's important 🎀

✨ NAME ✨

v4l2_m2m_release — the function that cleans up and frees a m2m_dev structure 🧹💀

🌸 SYNOPSIS 🌸

void v4l2_m2m_release (struct v4l2_m2m_dev *m2m_dev );

🦋 ARGUMENTS 🦋

  • m2m_dev — an opaque pointer to the internal data you use to handle the M2M context. opaque!! you don't peek inside, you just hand her over 👀🫶

💅 DESCRIPTION 💅

So basically: this is the function that cleans up and frees that m2m_dev structure. She's the closer, the last one out the group chat, turning off the lights 🔥

Usually called from the driver's remove function. That's it, that's the vibe — when your driver dips, v4l2_m2m_release handles the cleanup so nothing leaks. no cap, it's giving responsible main character energy 👑
