Hi Dan,

First of all,  sorry for late reply.

There is one issue. About this issue, I already discussed on patch[1]
[1] https://lore.kernel.org/lkml/5BEB63C3.1020504@samsung.com/ (local) 

extcon_get_extcon_dev() is used for anywhere except for probe step.
But EPROBE_DEFER is only used on probe step.

So that it is not clear to return EPROBE_DEFER from extcon_get_extcon_dev()
because extcon_get_extcon_dev() never know either call it on probe function
or not.

Currently extcon_get_extcon_dev() is only called from probe so it's not
an issue.

It's impossible to know what future programmers will want, but I feel
like this change probably makes it easier for them.

regards,
dan carpenter
