Commit8c3170628a("wifi: brcmfmac: keep power during suspend if board requires it") changed default behavior of the BRCMFMAC driver, which now keeps SDIO card powered during system suspend to enable optional support for WOWL. This feature is not supported by the legacy Exynos4 based boards and leads to WLAN disfunction after system suspend/resume cycle. Fix this by annotating SDIO host used by WLAN chip with 'cap-power-off-card' property, which should have been there from the beginning.

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 reStructuredText 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.
