ufshcd_set_variant(9)

💅 ufshcd_set_variant(9) — like, the Kernel API Manual page, bestie ✨

okay so picture this: it's a Kernel API Manual page, it's called ufshcd_set_variant(9), and it's genuinely so short you could read it in the time it takes to microwave a bagel 🥯. But it's a baddie of a function and it does exactly one job, so let's get into it.

---

🌸 NAME 🌸

ufshcd_set_variant — sets the variant-specific data onto the hba 💅 like that's literally the whole personality

---

✨ SYNOPSIS ✨

void ufshcd_set_variant (struct ufs_hba *hba , void *variant );

it returns void, so like… don't go looking for a return value, she gives you nothing back and she's iconic for it 👑

---

🎀 ARGUMENTS 🎀

• hba — the per adapter instance 🫶 yes, per adapter, each one gets its own, don't be weird about it
• variant — a pointer to the variant specific data 🦋 that's it, that's the pointer, it's just vibes and a void *

---

💜 SEE ALSO 💜

okay this is the part where the page goes FULL main character and name-drops literally everyone in the group chat 😭 and yes, we're listing every single one, no skipping, no "etc.", because bestie we do NOT do that here:

Kernel file ./include/ufs/ufshcd.h and also:

• struct uic_command(9)
• struct ufshcd_lrb(9)
• struct ufs_query_req(9)
• struct ufs_query_res(9)
• struct ufs_query(9)
• struct ufs_dev_cmd(9)
• struct ufs_clk_info(9)
• struct tx_eqtr_iter(9)

• ufshcd_get_variant(9)

like, the whole friend group showed up to the function's birthday party 🌈🎂 and ufshcd_get_variant(9) is right there at the end being the obvious counterpart — the getter to this setter, iykyk 😌

lowkey a whole vibe check of a page: ./include/ufs, October 2026 — that's where she lives and when she was last seen out 💀✨ slay, go set that variant, bestie 🫶💖🎀
