[PATCH v2 0/5] usb: Replace the deprecated extcon API

[Chanwoo Choi]

These patches replace the deprecated extcon API and remove them from extcon.

Patch4 (drivers/usb/gadget/udc/snps_udc_plat.c) neeeds the review
from usb maintainer. After finishing the review of patch4,
I'll create the immutable branch and send the pull request
to both usb and phy maintainer.

Changes from v1:
- Fix capital error for 'acked-by' tag on patch2
- Add the acked-by tag of 'Kishon Vijay Abraham I' to patch3

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

[Chanwoo Choi]

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.

The commit 575c2b867ee0 ("extcon: Rename the extcon_set/get_state()

following: But, the extcon just keeps the old API to prevent the build error.
This patch removes the deprecatd extcon API.

- extcon_set_cable_state_() -> extcon_set_state_sync()
