ufshcd_dev_cmd_completion(9)

hey bestie!! welcome to the ufshcd_dev_cmd_completion(9) page from the Kernel API Manual — yes, that whole mouthful is the manual name, and we are gonna get through it together 💖

✨ NAME ✨

ufshcd_dev_cmd_completion — handles device management command responses. It's literally the response-handling moment for device management commands, and the kernel-doc girlies said "put it in the manual" 🎀

🦋 SYNOPSIS 🦋

int ufshcd_dev_cmd_completion (struct ufs_hba *hba , struct ufshcd_lrb *lrbp );

🌸 ARGUMENTS 🌸

• hba — per adapter instance, aka the adapter's own little instance. Slay.
• lrbp — pointer to local reference block. Not me calling it a pointer bestie, that's just what it is 💅

⭐ RETURN ⭐

0 upon success; < 0 upon failure. That's the whole vibe check: zero means we ate, negative means something is giving error 😭

bestie, this list is huge on purpose — it's the SEE ALSO section, not a drill 💀

xoxo, your kernel-doc bestie 💖 — this page is from source/version ./drivers/ufs/core, dated October 2026, and it's iconic, periodt.
