v2: rephrase patch subject
call gpio_set_debounce before registering extcon device,
and set debounce_jiffies only if the call was not successful

I'd like you to add patch description for patch feature.
So I add a little description about using gpio_set_debounce()

I modify patch name as following to maintain patch naming style of extcon.
Before
extcon-gpio: Do not unnecessarily initialize variables
extcon-gpio: Use gpio driver/chip debounce if supported
After
extcon: gpio: Do not unnecessarily initialize variables
extcon: gpio: Use gpio driver/chip debounce if supported

No problem. I'll try to remember next time. Too late for patch 3/6, though.
Sorry for that.

Applied it on extcon-linus.
You can check it on extcon-linus branch in a few minutes.

Thanks,
Guenter
