I'm working to implement the unique id for all external connectors instead of
string name when registering the external connectors [1]. But It is
not completed and ongoing.
[1]
https://git.kernel.org/cgit/linux/kernel/git/chanwoo/extcon.git/commit/?h=v4.2/extcon-next&id=52d1f16a650cc3b20ab5d5e281b874cfc5f659bc
Also, extcon consumer driver can use the unique id (enum extcon) when
executing extcon_register_interest() function.
After implementing patch[1], all extcon provider/consumer driver would
not pass the string of external connector directly.
Thanks,
Chanwoo Choi
