okay so bestie, welcome to the kernel API manual, and honestly? you're about to learn about the most specific little function ever. no cap, it's giving "hyper-focused icon" energy. ✨

✨ NAME ✨

spi_nor_smpt_addr_nbytes — returns the number of address bytes used in the configuration detection command. that's it. that's the whole job. and she does it flawlessly. 💖

🦋 SYNOPSIS 🦋

u8 spi_nor_smpt_addr_nbytes (const struct spi_nor *nor , const u32 settings );

🌸 ARGUMENTS 🌸

• nor — this is a pointer to a struct spi_nor. like, the main character of your SPI NOR journey. you're passing her in so she can do her thing. 🫶
• settings — the configuration detection command descriptor, specifically dword1. this is the VIP pass that tells the function what's up. slay. 💅
