This is OK.  Please check this in to fix the reported build issues.

A couple of minor issues:

> +   Return 0 if succeed.  */

I think proper English usage would be "Return 0 on success." or
"Return 0 if sucessful."  (Here and elsewhere in the patch.)

Typo "initilzied".

Otherwise, this is OK as well.

Two other things as an aside:

- When committing a patch to git, please add the ChangeLog to the
  git commit message as well.  Have a look with "git log" at the
  existing practice how to format the commit messages for GDB.

- Given that you've now got commit access, please also add your name
  to the MAINTAINERS file under "Write After Approval"; see here for
  a recent example:
