Newest kernel appears to break tap feature - good starting point for kernel development?

Hi all,

I'm interested in getting involved in kernel development. I compiled the
latest kernel and found that it broke the tap feature on my asus x54h
k54l. I had a look at the way the devices were interpreted and
/proc/bus/input/devices gave different results. This seems like it may
be a good starting point but I'm not sure where to go from here or
whether it's an issue with the kernel. I presume it is as switching back
to the older kernel fixes the tapping for left click.

Likely you found regression here.

I think the key here is by using git feature called "bisect" to find
out the culprit. This might require repetitive kernel build and re
test. It's kinda trial work, only here you got help from git as the
revision control.

Once you found the commit that introduce the bug, you can either
remove that (of course, without introducing instability) or improve
it.

It all might sound easy, but require patience and time.
