Guillaume Ranquet 4467b8bad2 clocksource/drivers/timer-of: Check return value of of_iomap in timer_of_base_init()
of_base->base can either be iomapped using of_io_request_and_map() or
of_iomap() depending whether or not an of_base->name has been set.

Thus check of_base->base against NULL as of_iomap() does not return a
PTR_ERR() in case of error.

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.
