cvs_runtime_suspend(9) — Kernel API Manual 🦋

okay bestie, welcome to the cvs_runtime_suspend(9) page in the Kernel API Manual. This is the runtime PM suspend moment, and it is literally about handing the CSI-2 link back. No cap, it’s a tiny function with main character energy. 💅

✨ NAME ✨

cvs_runtime_suspend — Runtime PM suspend: release CSI-2 link ownership 🎀

✨ SYNOPSIS ✨

int cvs_runtime_suspend (struct device *dev );

✨ ARGUMENTS ✨

• dev — Device. That’s the device you’re passing in, bestie. 🫶

✨ DESCRIPTION ✨

Called when the streaming reference is dropped by cvs_csi_disable_streams via pm_runtime_put_autosuspend. It returns CSI-2 link ownership to CVS firmware. It’s giving “clean up your room and give the aux back” energy, fr fr. 🌸

✨ RETURN ✨

0 on success or negative errno. So 0 is the slay case; a negative errno is the “not today” case. 😭
