As covered in submitting-patches.rst your diff should be against the
root of the kernel tree rather than files in a subdirectory, look at how
other patches on the list are being formatted for examples of how things
look.  If you use git format-patch to generate patches it should do the
right thing for you.

The fact that you're describing three different changes changes here
suggests that this should be a patch series rather than a single patch,
as covered in submitting-patches.rst this is the general style for Linux
as it makes things much easier to review.  Each logical change should be
a separate patch.

This is an on/off switch, it should be a normal boolean control ending
in Switch and taking 0 and 1 as valid values.

The issues with use of hungarian notation and not generating events that
were present previously remain.

Please don't ignore review comments, people are generally making them
for a reason and are likely to have the same concerns if issues remain
unaddressed.  Having to repeat the same comments can get repetitive and
make people question the value of time spent reviewing.  If you disagree
with the review comments that's fine but you need to reply and discuss
your concerns so that the reviewer can understand your decisions.

Please don't send cover letters for single patches, if there is anything
that needs saying put it in the changelog of the patch or after the ---
if it's administrative stuff.  This reduces mail volume and ensures that 
any important information is recorded in the changelog rather than being
lost.
