edac_device_del_device(9)

💅 edac_device_del_device 💅

okay so bestie, this is a page from the Kernel API Manual and it's literally about ✨cleaning up✨ — like when you finally delete that situationship from your phone. only here the situationship is an edac_device and the phone is sysfs. iconic behaviour honestly 🎀

🌸 NAME 🌸

edac_device_del_device — removes the sysfs entries for the edac_device structure you point at, and then yeets that edac_device structure right out of the global list. bye bestie 👋💖

✨ SYNOPSIS ✨

struct edac_device_ctl_info * edac_device_del_device (struct device *dev);

🦋 ARGUMENTS 🦋

• dev — a pointer to a struct device that represents the edac device structure you wanna remove. that's the whole assignment, she's simple like that 💅

⭐ RETURN ⭐

it hands you back a pointer to the removed edac_device structure 🫶 … or NULL if the device wasn't found 😭 (not me checking for NULL, always check for NULL).

no cap, NULL here means "couldn't find it", so don't go dereferencing it like it's main character energy. 🙈
