module_spi_driver(9)

module_spi_driver(9) — the Kernel API Manual page, but make it cute

okay so bestie, this is the module_spi_driver(9) page from the Kernel API Manual, and it is literally the low-effort icon for SPI driver modules. no cap. 💅

💖 NAME 💖

module_spi_driver — helper macro for registering a SPI driver. that’s the whole vibe. ✨

✨ SYNOPSIS ✨

module_spi_driver (__spi_driver );

🌸 ARGUMENTS 🌸

• __spi_driver — a spi_driver struct. that’s the one and only argument, bestie 🫶

🦋 DESCRIPTION 🦋

This macro is the helper for SPI drivers that do not do anything special in module init/exit. it eliminates a lot of boilerplate — the way it eats copy-paste for breakfast, honestly iconic 🍓✨

Each module may only use this macro once, and calling it replaces module_init and module_exit. not me emphasizing “once” — yes, once. periodt. 💀
