🎀 NAME 🎀

spinand_user_otp_read — read from the OTP area 🦋

---

🌸 SYNOPSIS 🌸

int spinand_user_otp_read (struct spinand_device *spinand , loff_t ofs ,
size_t len , size_t *retlen , u8 *buf );

---

💖 ARGUMENTS 💖

• spinand — the spinand device, aka the main character of this whole function 👑
• ofs — the offset to read from, like where you're starting your little scroll 📍
• len — the number of data bytes to read, so the size of the snack you're grabbing 🍓
• retlen — the pointer to the variable that stores the number of read bytes, so you know how many bytes actually showed up 🙈
• buf — the buffer to store the read data, aka the bag where all the bytes go 🎀
