v5 -> v6:
- Add the missed change to EPOLLIN.
v4 -> v5:
- Simplify the commit title and message.
- Change the 'MODULE_DEVICE_TABLE' position.
v3 -> v4:
- Correct the header file's macro defination end comment which is old
file name, I forgot to change it after changing the file name.
- Remove the space between the comment words and colon.
v2 -> v3:
- Make the commit message be more understandable.
v1 -> v2:
- Add 'SPDX-License-Identifier' style for header files modification.

Sorry for the delay, I was on jury duty last week. But it looks like
you got
some useful changes in.
I'm hoping you are done with this patch :-). I've included in my tree, but
I can replace if necessary.
Thanks,
