Switch to the new generic framework by updating function signatures and define a "struct dev_pm_ops" variable to bind PM callbacks. This way we can remove the legacy .suspend & .resume bindings from "lxfb_driver". The lxfb_suspend() is designed to function only in the case of Suspend. Thus, the code was kept inside "if (state.event == PM_EVENT_SUSPEND)" container. This is because, in the legacy framework, this callback was invoked even in the event of Freeze and Hibernate. Hence, added the load of unnecessary function-calls. The goal can be achieved by binding the callback with only "lxfb_pm_ops.suspend" in the new framework. This also avoids the step of checking "if (state.event == PM_EVENT_SUSPEND)" every time the callback is invoked.

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.
