pm_runtime_no_callbacks(9)

💅 NAME 💅

okay bestie, meet pm_runtime_no_callbacks(9) from the Kernel API Manual — the little function that tells runtime PM to ignore callbacks for a device. It's short, it's iconic, it's literally the "not me having my own callbacks" of kernel power management. 💖

✨ SYNOPSIS ✨

void pm_runtime_no_callbacks (struct device *dev );

🎀 ARGUMENTS 🎀

• dev — the device to handle, bestie. That's the one this call is about.

🦋 DESCRIPTION 🦋

So here's the tea: this sets the power.no_callbacks flag, which tells the PM core that this device is power-managed through its parent and has no runtime PM callbacks of its own. No cap. ✨

Also? The runtime sysfs attributes will be removed. That's the whole situation, and it's lowkey iconic. 💅
