okay so bestie, welcome to the Kernel API Manual 💖 you're literally about to meet struct stm32_dac, and honestly? it's giving "quiet private data of the DAC driver" energy and we respect it 🫶

🌸 NAME 🌸

struct stm32_dac — the private data of the DAC driver 💅 no cap, that's the whole vibe

 };

look at her. two members. iconic. not a single wasted field 😭

🎀 Members 🎀

• common — a reference to the DAC common data ✨ like, it's the shared stuff, and she's holding the pointer to it. lowkey essential.
