spi_nor_spimem_exec_op(9)

💅 spi_nor_spimem_exec_op — the Kernel API Manual, bestie edition 🎀

Okay so real talk, this is one of those little helper functions in the Linux kernel's SPI-NOR driver world. It does exactly one job and it does it slayfully. The full manpage name is spi_nor_spimem_exec_op(9), and honestly? Iconic. Let's get into it. ✨

🌸 NAME 🌸

spi_nor_spimem_exec_op — execute a memory operation 💫

🦋 SYNOPSIS 🦋

int spi_nor_spimem_exec_op (struct spi_nor *nor , struct spi_mem_op *op
);

💖 ARGUMENTS 💖

• nor — pointer to 'struct spi_nor' 🫶 (this is your NOR flash cutie, the main character)
• op — pointer to 'struct spi_mem_op' template for transfer 🌈 (this is the blueprint for whatever memory op you're about to send out)

⭐ RETURN ⭐

0 on success, and -error otherwise. Fr fr, zero means we ate, negative means something went sideways. 😭
