pm_runtime_put(9)

💅 pm_runtime_put 💅

okay so this is the Kernel API Manual entry for pm_runtime_put, and it's lowkey iconic. bestie, it's giving “drop the counter, maybe queue the idle check” energy, and the vibes are immaculate.

🌸 NAME 🌸

pm_runtime_put — drop device usage counter and queue up "idle check" if 0.

✨ SYNOPSIS ✨

void pm_runtime_put (struct device *dev );

🎀 ARGUMENTS 🎀

• dev — target device. that's the one, bestie.

🦋 DESCRIPTION 🦋

okay so here's the whole plot: decrement the runtime PM usage counter of dev, and if it turns out to be equal to 0, queue up a work item for dev like in pm_request_idle. that's literally it. no extra steps, no cap. 💅
