sca3000_reg_lock_on(9)

💅 sca3000_reg_lock_on(9) — a Kernel API Manual moment ✨

okay so bestie, welcome to the kernel API manual (that's the manual name btw, we're in it 💖) and today's main character is sca3000_reg_lock_on. she's small, she's specific, she's iconic in a very niche way. let's get into it 🎀

---

✨ NAME ✨

sca3000_reg_lock_on — literally just: test if the ctrl register lock is on. that's it. that's the whole vibe check 🔥

---

🦋 SYNOPSIS 🦋

int sca3000_reg_lock_on (struct sca3000_state *st );

yes bestie, that's the whole signature. int out, one struct pointer in. slay 🌸

---

🎀 ARGUMENTS 🎀

• st — the driver specific device instance data. like, your device's little bundle of state. driver-specific, so she knows things about her device that other devices don't. no cap 💜

---

👑 DESCRIPTION 👑

so here's the thing: the lock must be held. that's not a suggestion, that's not a "try your best", that's the rule. lock held, or you're not invited to the party 🙈

🌈 SEE ALSO 🌈

the kernel file lives at ./drivers/iio/accel/sca3000.c and honestly there's a whole squad over there, so go say hi 👋:

• struct sca3000_chip_info(9)
• __sca3000_unlock_reg_lock(9)
• sca3000_write_ctrl_reg(9)

that's the whole friend group bestie, not me listing them all and then skipping some — every single one made the list 🫶

also a lil reminder ok: before you call this one, the lock must be held. i said it once in DESCRIPTION and i'm saying it again because it's the whole point 💀

and that's the page!! cute little sign-off for you: this one comes from ./drivers/iio/accel (that's the source, bestie) and she's dated October 2026 for the version vibe. mwah 💋✨
