cdns_ufs_lin...artup_notify(9)

💅 cdns_ufs_link_startup_notify — NAME ✨

okay so bestie, this is a page from the Kernel API Manual (yup, the big-kid docs, not the vibe-only ones) and it's about cdns_ufs_link_startup_notify — like, literally the function that handles link startup. that's the whole job. it shows up when the UFS link is getting its little life together and somebody has to be the responsible one. 🦋

---

🌸 SYNOPSIS 🌸

int cdns_ufs_link_startup_notify (struct ufs_hba *hba , enum
       ufs_notify_change_status status );

no cap, that's the signature, character for character. don't @ me, just copy it exactly. ✨

---

🎀 ARGUMENTS 🎀

• hba — the host controller instance, aka the main character of this whole situation 👑
• status — the notify stage, and it's giving pre and post change, so like the before-and-after of the glow-up 💅

---

💖 RETURN 💖

zero means success (slay 🎉), non-zero means failure (💀). that's it. that's the whole vibe check.
