Dmitry thanks for your comment. I deleted all my changes except one
and prepare a new patch for it. 

In function input_set_capability when it go through default statment 
it is use hard coded function name "input_set_capability" in pr_err() call.
I replace it using "%s" __func__ instead.

Change hardcoded string "input_set_capability"

"%s" __func__ instead.
