ec_i2c_parse_response(9)

💅 ec_i2c_parse_response(9) — like, the whole vibe 🦋

okay so bestie, this is a page from the Kernel API Manual, section 9, and it's about ec_i2c_parse_response — yes that's the whole name, it's giving "long function name energy" and we're obsessed. let's get into it ✨

---

🌸 NAME 🌸

ec_i2c_parse_response — literally just: Parse a response from the EC. that's it. that's the whole name section. iconic brevity 💅

---

🎀 SYNOPSIS 🎀

int ec_i2c_parse_response (const u8 *buf , struct i2c_msg i2c_msgs[] ,
int *num );

no cap, that's the signature, copy it exactly, don't get creative with it 🙈

---

✨ ARGUMENTS ✨

• buf — the buffer you're parsing. that's the thing going in 🫶
• i2c_msgs — the i2c messages to fill up. it's the empty cup, you're pouring into it 🍓
• num — the number of i2c messages. heads up though: this gets modified to include the actual number received 😭 so like, don't be surprised when it comes back different, it's supposed to do that

---

💖 DESCRIPTION 💖

so the plan is simple: we take the EC's response and copy it back into msgs. that's the whole bit. lowkey elegant ngl ✨

it returns 0 or a negative error number — so zero means slay, negative means something went wrong, and you should probably go look at it 💀

and that's the page!! mwah 💋

this little gem lives over in ./drivers/i2c/busses, and the version we're looking at is dated October 2026 — so go forth, parse those responses, and remember: negative error numbers are not a personality trait, bestie 💜 🧚
