Change clock member in mlx5_core_dev to a pointer, so it can point to a clock shared by multiple functions in later patch. For now, each function has its own clock, so mdev in mlx5_clock_priv is the back pointer to the function. Later it points to one (normally the first one) of the multiple functions sharing the same clock. Change mlx5_init_clock() to return error if mlx5_clock is not allocated. Besides, a null clock is defined and used when hardware clock is not supported. So, the clock pointer is always pointing to something valid.

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.
