Brian Norris 8d1191f924 clk: fix leak on devm_clk_bulk_get_all() unwind 
commit f828b0bcacef189edbd247e9f48864fc36bfbe33 upstream.

clk_bulk_get_all() allocates an array of struct clk_bulk data for us
(unlike clk_bulk_get()), so we need to free it. Let's use the
clk_bulk_put_all() helper.

kmemleak complains, on an RK3399 Gru/Kevin system:

unreferenced object 0xffffff80045def00 (size 128):

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.
