🌸 SYNOPSIS 🌸

int extcon_set_state_sync (struct extcon_dev *edev , unsigned int id ,
       bool state );

like look at that signature. chef's kiss. no cap.

🦋 ARGUMENTS 🦋

• edev — the extcon device, aka the main character of this whole situation 🫶
• id — the unique id that points at one specific external connector. it's the little name tag, iykyk 💅
• state — the new state of the external connector. the default semantics is literally true: attached / false: detached. so true = they're together 💖 and false = it's giving distance 😭

🔥 DESCRIPTION 🔥

okay so real talk — note that this function sets the state of the external connector and synchronizes the state by sending a notification. it doesn't just change the vibe quietly, it tells everyone. lowkey the most extroverted function in the file.

Returns 0 if success or error number if fail. so 0 = slay, anything else = check yourself bestie 💀
