sdhci_arasa...gister_sdclk(9)

💅 sdhci_arasan_unregister_sdclk(9)

okay bestie, welcome to the Kernel API Manual ✨ this one's a tiny little cleanup function and honestly it's giving responsible main character energy. it's in section 9, and no cap, it's short — but every word matters 🎀

---

🌸 NAME

sdhci_arasan_unregister_sdclk — the undo button for sdhci_arasan_register_sdclk() 🫶

---

✨ SYNOPSIS

void sdhci_arasan_unregister_sdclk (struct device *dev );

that's it. that's the whole vibe. one arg, returns nothing, no drama 💅

---

🦋 ARGUMENTS

• dev — pointer to our struct device. like, the device that owns this whole situation. it's literally the struct device * you hand over so the function knows whose clock registration to tear down 💖

---

🌈 DESCRIPTION

okay so here's the tea 🍵: you call this bad boy any time we're exiting — and only when sdhci_arasan_register_sdclk returned success. that's it, that's the contract.

let me say it again with feeling: this is the cleanup counterpart. it undoes what sdhci_arasan_register_sdclk() did. if the register call didn't succeed, there's nothing to un-register, so don't come for this function 🙈

⚠️ vibe check: this is an exit-path function. it's the "we're leaving, tidy up" moment. treat it like turning off the lights on your way out — not something you spam mid-party 💀
