STRUCT ADXRS450_STATE(9)

✨ struct adxrs450_state(9) ✨

okay so bestie, welcome to the Kernel API Manual page for struct adxrs450_state — it's giving "device instance specific data" and honestly? iconic. this is the little struct that holds everything one specific ADXRS450 gyro instance needs to know about itself 🎀

---

🌸 NAME 🌸

struct adxrs450_state — device instance specific data 💅

like, the per-device vibes container. no cap.

---

🦋 SYNOPSIS 🦋

struct adxrs450_state {
    struct spi_device       *us;
    struct mutex            buf_lock;
    __be32 tx;
    __be32 rx;
 };

that's the whole struct, and yes the way that closing brace is indented in the original is a whole mood — we keep it exactly as it is, periodt ✨

---

💖 Members 💖

so here's the breakdown, member by member, no skips:

• us — the actual spi_device. your real hardware bestie 🫶
• buf_lock — a mutex whose whole job is to protect tx and rx. it's the bouncer at the door of your buffers, fr fr 🔒
• tx — the transmit buffer 💌
• rx — the receive buffer 💌

ngl, buf_lock is main character energy: without it, tx and rx are just two fields with zero chill. keep them locked, bestie.
