💅 prepare_cros_ec_rx(9) — Kernel API Manual 💅

okay so we're in the Kernel API Manual and this page is all about prepare_cros_ec_rx(9). Group-chat intro over, let's get into it. ✨

🌸 NAME 🌸

prepare_cros_ec_rx — check & prepare receive buffer. That's the name, no cap. 💖

✨ SYNOPSIS ✨

int prepare_cros_ec_rx (struct cros_ec_device *ec_dev , const struct
cros_ish_in_msg *in_msg , struct cros_ec_command *msg );

🎀 ARGUMENTS 🎀

• ec_dev — the CrOS EC MFD device. That's the device in question, bestie. 🫶
• in_msg — incoming message buffer. It's literally the message coming in. 📥
• msg — the cros_ec command used to send & receive data. It's the command vibe for the send/receive situation. 🔁

💫 RETURN 💫

• 0 for success. Slay. ✅
• negative error code for failure. Not slay, but at least it's honest. 😭

🦋 DESCRIPTION 🦋

It checks the received buffer, then converts it to cros_ec_command format. That's the glow-up: received buffer in, cros_ec_command format out. 💅
