STRUCT V4L2_SUBDEV_CAPABILITY(9)

okay so bestie, this is the Kernel API Manual page for struct v4l2_subdev_capability(9) — and it is lowkey iconic how much this little struct is doing ✨💅

✨ NAME ✨

struct v4l2_subdev_capability — subdev capabilities. That's the name, that's the vibe, no notes 🎀

🦋 SYNOPSIS 🦋

Here is the struct exactly as the page serves it, no copy-paste crimes, no edits:

struct v4l2_subdev_capability {
    __u32 version;
    __u32 capabilities;
    __u32 reserved[14];
 };

💅 Members 💅

Three members, all __u32, all doing their little thing:

• version — the driver versioning number. Literally the driver's version number, bestie 🫶
• capabilities — the subdev capabilities, see V4L2_SUBDEV_CAP_* 👀
• reserved (__u32 reserved[14];) — for future use, set to zero for now 🙈
