brcmfmac assumed the wifi device always remains powered on and thus hardcoded the MMC_PM_KEEP_POWER flag expecting the wifi device to remain on even during suspend/resume cycles. This is not always the case, some appliances cut power to everything connected via SDIO for efficiency reasons and this leads to wifi not being usable after coming out of suspend because the device was not correctly reinitialized. So we check for the keep_power capability and if it's not present then we remove the device and probe it again during resume to mirror what's happening in hardware and ensure correct reinitialization in the case when MMC_PM_KEEP_POWER is not supported.

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.
