i3c_i2c_driver_unregister(9)

💅 i3c_i2c_driver_unregister(9) — the Kernel API Manual page, but make it make sense

okay so bestie, welcome to the Kernel API Manual ✨ — today's main character is i3c_i2c_driver_unregister, and honestly? her whole job is saying "you're done here" to two drivers at once. no cap, it's giving cleanup era 🧹💖

---

✨ NAME ✨

i3c_i2c_driver_unregister — unregister an i2c and an i3c driver 🫶

like, both of them. together. one function call, two drivers exiting the chat 💀

---

🌸 SYNOPSIS 🌸

void i3c_i2c_driver_unregister (struct i3c_driver *i3cdrv , struct
i2c_driver *i2cdrv );

look at her go, she takes two pointers and returns literally nothing (void, we love a queen who doesn't overpromise) 💅

---

🦋 ARGUMENTS 🦋

• i3cdrv — the I3C driver to register 👑

okay so the manpage literally says "to register" here and we're just passing that along verbatim, don't come for me 🙈 the icon said what she said

• i2cdrv — the I2C driver to register 🎀

same situation, same energy, keeping it exactly as written fr fr

Two args, both drivers, no extras. Iconic. 🌈

---

💜 DESCRIPTION 💜

so this function unregisters both i3cdrv and i2cdrv at once. two birds, one function call, zero drama. ✨

but here's the plot twist you need to know: when CONFIG_I3C is not enabled, this function only unregisters the i2cdrv. 😭 that's it. the I3C half just doesn't happen. so if your mental model was "both always get unregistered," bestie, do a little vibe check on your config first 🔥

💀 friendly reminder that this is the unregister page — she undoes things. the "to register" wording in ARGUMENTS is straight from the source, not a typo of mine, okurrr 🙈

and that's the whole page bestie, you ate that 🍓 mwah 💋
