Suppose I have same version of linux kernel but I changed some driver lines. Is there any way to compare these kernels and list the results. The result would be helpful to go back if I changed a lot in original drivers.

The traditional method:

diff -r dir1  dir2 

That gives you a file-by-file difference, which can be kind of wordy. If you have Gnu diff, you can try:

diff -r --brief dir1 dir2
