💖 tpm_cr50_i2c_tis_send 💖

okay so bestie, welcome to the Kernel API Manual entry for tpm_cr50_i2c_tis_send — literally the TPM transmission callback. that's it, that's the whole vibe. it sends. it's a callback. iconic behaviour tbh 🎀

✨ NAME ✨

tpm_cr50_i2c_tis_send — the TPM transmission callback. no cap, that's what it does 🦋

---

🌸 SYNOPSIS 🌸

int tpm_cr50_i2c_tis_send (struct tpm_chip *chip , u8 *buf , size_t
bufsiz , size_t len );

like… look at her. four args, one int return, zero notes. she's giving minimalism 💅

---

🫶 ARGUMENTS 🫶

• chip — a TPM chip. yes. the actual chip struct. your main character 🧚
• buf — the buffer you wanna send. the payload. the moment 🔥
• bufsiz — the buffer size. how much room buf actually has, don't lie about it 🙈
• len — the command length. how much of that buffer is real command and not just vibes ⭐

---

👑 RETURN 👑

• 0 — success. we ate. periodt 💖
• -errno — a POSIX error code. so if it's not 0, it's one of those negative numbers and something went sideways 😭
