pm_runtime handles sdio power on and power off transitions. An old workaround for trying to control the power explicitly from the driver was in fact causing failures on suspend/resume as the mmc layer already power the module on resume. In case of resume pm_runtime_get sync returns a positive device's usage count causing the driver to try an re-initialize an already initialized device. This was causing sdio bus failure on resume. Remove this manual power on/off sequence as it is in-fact not needed.

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.
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.
