As per the current implementation of only single callback data gets saved per event, driver is throwing an error if try to register multiple callback for same event. Add support of multiple callbacks data for same event. So agent can register for same event with multiple callbacks. Here event management driver will store the callbacks as list in Hash table entry for that event. Here each callback data contain 2 element as callback handler and private data of agent driver.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
