Subject: [PATCH net-next 2/4] nfc: s3fwrn5: reduce the EN_WAIT_TIME

From: Bongsu Jeon <[email protected]>

The delay of 20ms is enough to enable and
wake up the Samsung's nfc chip.

It's really not easy to work with your way of sending the patches.

I am sorry but you have to adjust your style to the style of reviewers
and the entire community.

1. Again, you ignored/dropped my Ack.

2. I asked you to send all patches referencing each other, which you can
achieve without any effort with git format-patch and send-email or
with in-reply-to.
Seriously, these tools work properly by default! You have to break
them on purpose - so stop. Now, all your patches are scattered over
my mailbox. They are all over mailing list:
https://lore.kernel.org/lkml/?q=bongsu.jeon2%40gmail.com
Browsing this patchset is uncomfortable. It's a pain.

Please, work on your workflow. Get help in that - there are plenty of
open-source contributors in Samsung. Ask them how to do it. If you
cannot, read the mailing lists and see how others do it.

Recent example, one of thousands:
https://lore.kernel.org/linux-arm-kernel/[email protected]/T/#m4a9ed644869b8018b8286a6b229012278141cb66

1. It comes with a cover letter,
2. All emails are properly linked with each other (scroll to the bottom).

Best regards,
Krzysztof
