Subject: Re: [PATCH v2 4/5] usb: gadget: udc: Replace the deprecated extcon
 API

Ping.

Hi Felipe,

I sent the first patch[1] more than three weeks ago.
But I didn't receive the any review.
[1] https://lkml.org/lkml/2017/7/16/523

This patch is very simple. After finishing the review
I'll remove the deprecated extcon API and then send
the immutable branch to both phy and usb maintainer.


Usually, I send the extcon's pull request to the GregKH
for the next merge after releasing 4.x-rc6.
(4.x-rc4 was released)

Please review this patch.
