_shutdown(9)

💅 _shutdown(9) 💅

Hii bestie, welcome to the Kernel API Manual page for _shutdown 🫶 This is the kernel function that shuts down an omap_hwmod, and we’re gonna read it together like a group chat. No cap.

🌸 NAME 🌸

_shutdown — shutdown an omap_hwmod. That’s literally the whole name vibe: it shuts down an omap_hwmod 💖

✨ SYNOPSIS ✨

int _shutdown (struct omap_hwmod *oh );

🎀 ARGUMENTS 🎀

• oh — a struct omap_hwmod *. This is the hwmod that’s getting shut down, periodt. 🦋

💅 DESCRIPTION 💅

Okay so _shutdown shuts down an omap_hwmod oh. This should be called when the driver used for the hwmod is removed or unloaded, or if the driver is not used by the system 🧚

Return value tea: it returns -EINVAL if the hwmod is in the wrong state, or returns 0. That’s the whole situation, bestie 💀
