coresight_get_ref(9)

💖 coresight_get_ref 💖

okay bestie, welcome to the Kernel API Manual corner of the group chat 🫶. This one is coresight_get_ref, and it's giving “tiny helper with refcount responsibilities.” no cap. ✨

✨ NAME ✨

coresight_get_ref — helper function to increase the reference count to the module and device. 💅

🌸 SYNOPSIS 🌸

bool coresight_get_ref (struct coresight_device *csdev );

🎀 ARGUMENTS 🎀

• csdev — the coresight device to get a reference on. literally the main character here 🦋

🦋 DESCRIPTION 🦋

Here's the vibe check, bestie:

• it returns true in the successful case and powers up the device ✨
• it returns false when it fails to get a reference of the module 😭

no cap: success = true + device power-up; failure = false because the module reference didn't happen. periodt.
