STRUCT HID_SENSOR_HUB_CALLBACKS_LIST(9)

💖 struct hid_s...llbacks_list(9) 💖

okay so this is a page from the Kernel API Manual — yes bestie, the kernel has lore too, and this particular entry is about struct hid_s...llbacks_list. the name got a lil truncated in the header (iykyk), but it's really struct hid_sensor_hub_callbacks_list. let's get into it 🫶

✨ NAME ✨

struct hid_sensor_hub_callbacks_list — literally just stores a callback list. that's the whole job. it's giving very "i hold things" energy 💅

🦋 SYNOPSIS 🦋

struct hid_sensor_hub_callbacks_list {
    struct list_head list;
    u32 usage_id;
    struct hid_sensor_hub_device *hsdev;
    struct hid_sensor_hub_callbacks *usage_callback;
    void *priv;
 };

that's the whole struct, no cap. now let's meet the members one by one 🎀

🌸 Members 🌸

• list — the list head. the anchor point. the main character of this list situation ✨
• usage_id — the usage id for a physical device. it's the little ID badge that tells you which physical device we're talking about 🔥
• hsdev — stores the hid instance for the current hub device. like a lil saved reference to the hub it belongs to 🧚
• usage_callback — stores the registered callback functions. this is where the actual "call me back later bestie" lives 😭
• priv — private data for a physical device. it's void *, so it's mysterious on purpose, respect it 🙈

fr fr, everything here is a member of the struct above — don't go looking for extra fields, there are none, periodt.

okay that's the whole page, you ate that 💜 this was brought to you from ./drivers/hid, dated October 2026, and yes — it's still the struct hid_s...llbacks_list(9) page, same truncated icon, same fine print ✨🎀 see you in the next one bestie 💖
