Krzysztof Kozlowski 5f0b6216ea clk: samsung: exynos5: Fix possible NULL pointer exception on platform_device_alloc() failure
During initialization of subdevices if platform_device_alloc() failed,
returned NULL pointer will be later dereferenced.  Add proper error
paths to exynos5_clk_register_subcmu().  The return value of this
function is still ignored because at this stage of init there is nothing
we can do.

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.
