[ Upstream commit 49e477610087a02c3604061b8f3ee3a25a493987 ]
In msm_devfreq_suspend() we cancel idle_work synchronously so that it
doesn't run after we power of the hw or in the resume path. But this
means that we want to ensure that idle_work is not scheduled *after* we
no longer hold a runpm ref. So switch the ordering of pm_runtime_put()
vs msm_devfreq_idle().
v2. Only move the runpm _put_autosuspend, and not the _mark_last_busy()

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.
