The calls to panfrost_devfreq_record_busy() and
panfrost_devfreq_record_idle() must be balanced to ensure that the
devfreq utilisation is correctly reported. But there are two cases where
this doesn't work correctly.
In panfrost_job_hw_submit() if pm_runtime_get_sync() fails or the
WARN_ON() fires then no call to panfrost_devfreq_record_busy() is made,
but when the job times out the corresponding _record_idle() call is
still made in panfrost_job_timedout(). Move the call up to ensure that
it always happens.
Secondly panfrost_job_timedout() only makes a single call to
panfrost_devfreq_record_idle() even if it is cleaning up multiple jobs.
Move the call inside the loop to ensure that the number of
_record_idle() calls matches the number of _record_busy() calls.

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.
