Subject: [PATCH] FROMLIST: input: add 2 kind of switch
We need support to various accessories on the device,
some switch does not exist in switch list.
So added switch for the following purpose.
SW_COVER_ATTACHED is for the checking the cover
attached or not on the device. SW_EXT_PEN_ATTACHED is for the
checking the external pen attached or not on the device

You sent this 3 times, why?
And why is this in the body of the email, have you read the "how to send
your first kernel patch" document at kernelnewbies.org?

As per the kernel documentation, you need to use your real name here,
please do so.

Is there an in-kernel user for these values anywhere? Please submit
this patch along with the users at the same time, otherwise this change
makes no sense at all.

It kind of does, as nowadays most uses come from DT, not from
hard-coding in drivers. However I need to better understand the intended
use of this. How SW_COVER_ATTACHED differs from SW_MACHINE_COVER and the
same for SW_PEN_INSERTED SW_EXT_PEN_ATTACHED.
Thanks.
