The validation for driver data pointers and clock pointers are redundant in the runtime PM callbacks. After a driver's probing, its driver data and clocks have been initialized successfully, this ensures it is safe to access driver data and clocks in the runtime PM callbacks. A corner case is a clock pointer is NULL, in this case, the clock core layer can handle it properly. So remove these redundant checking. In runtime resume, respect values returned from clock function and add error handling.

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 reStructuredText 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.
