Chaitanya Kulkarni 2ed9a89192 nvme-core: fix dev_pm_qos memleak
[ Upstream commit 7ed5cf8e6d ]

Call dev_pm_qos_hide_latency_tolerance() in the error unwind patch to
avoid following kmemleak:-

blktests (master) # kmemleak-clear; ./check nvme/044;
blktests (master) # kmemleak-scan ; kmemleak-show
nvme/044 (Test bi-directional authentication)                [passed]
    runtime  2.111s  ...  2.124s

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.
