mtd_oob_ops *ops );

she takes three things and returns an int, periodt. 🎀

🦋 ARGUMENTS 🦋

• mtd — the MTD device structure. the actual chip's whole deal. main character energy right here 👑
• from — offset to read from. where you're starting, lowkey your origin story 📍
• ops — the oob operation description structure. this one's holding all the details about the oob op you want 🫶
