Kishon Vijay Abraham I 5f17dcfa6d clk: Fix memory leak in clk_unregister()
commit 8247470772beb38822f226c99a2ed8c195f6b438 upstream.

Memory allocated in alloc_clk() for 'struct clk' and
'const char *con_id' while invoking clk_register() is never freed
in clk_unregister(), resulting in kmemleak showing the following
backtrace.

  backtrace:

Fix it here.

README

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.
