[ Upstream commit 2de5cb96060a1664880d65b120e59485a73588a8 ] In function `s5pv210_cpu_init`, a possible refcount inconsistency has been identified, causing a resource leak. Why it is a bug: 1. For every clk_get, there should be a matching clk_put on every successive error handling path. 2. After calling `clk_get(dmc1_clk)`, variable `dmc1_clk` will not be freed even if any error happens. How it is fixed: For every failed path, an extra goto label is added to ensure `dmc1_clk` will be freed regardlessly.

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.
