struct v4l2_flash {
    struct led_classdev_flash *fled_cdev;
    struct led_classdev *iled_cdev;

🎀 Members 🎀

now the member-by-member vibe check, one at a time, no skipping 🔥

• fled_cdev — the LED flash class device that this sub-device controls. she's the main character being driven here 💫
• iled_cdev — the LED class device representing the indicator LED that's associated with the LED flash class device. like, the little sidekick light 🍓
• ops — the V4L2 specific flash ops. the operations, the moves, the choreography ✨
• sd — the V4L2 sub-device itself. hi queen 👑
• hdl — the flash controls handler. someone's gotta handle the controls 💅
• ctrls — array of pointers to controls, whose values define the sub-device state. not me being an array of pointers 😭
