John Keeping e84b4a84e5 PM / QoS: Fix memory leak on resume_latency.notifiers 
Since commit 2d984ad132 (PM / QoS: Introcuce latency tolerance device
PM QoS type) we reassign "c" to point at qos->latency_tolerance before
freeing c->notifiers, but the notifiers field of latency_tolerance is
never used.

Restore the original behaviour of freeing the notifiers pointer on
qos->resume_latency, which is used, and fix the following kmemleak
warning.

README 

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
