Remove PS related *_irqsafe functions to avoid entering/leaving PS under interrupt context. Instead, make PS decision in watch_dog. This could simplify the logic and make the code look clean. But it could have a little side-effect that if the driver is having heavy traffic before the every-2-second watch_dog detect the traffic and decide to leave PS, the thoughput will be lower. Once traffic is detected by watch_dog and left PS state, the throughput will resume to the peak the hardware ought to have again.

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.
