Daniel Mack 7444a80929 libertas: fix suspend and resume for SDIO connected cards 
Prior to commit 573185cc7e ("mmc: core: Invoke sdio func driver's PM
callbacks from the sdio bus"), the MMC core used to call into the power
management functions of SDIO clients itself and removed the card if the
return code was non-zero. IOW, the mmc handled errors gracefully and didn't
upchain them to the pm core.

Since this change, the mmc core relies on generic power management
functions which treat all errors as a reason to cancel the suspend
immediately. This causes suspend attempts to fail when the libertas
driver is loaded.

To fix this, power down the card explicitly in if_sdio_suspend() when we
know we're about to lose power and return success. Also set a flag in these
cases, and power up the card again in if_sdio_resume().

Fixes: 573185cc7e ("mmc: core: Invoke sdio func driver's PM callbacks from the sdio bus")

README 

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.
